I have 2 new requests

1. A code that'll allow the music to be changed to a different track upon entering the options screen in Sonic Spinball (similar to the Puggsy music code I needed previously).

2. It seems Sonic 3's Launch Base Zone Act 1 was intended to have water at one point:
https://tcrf.net/Sonic_the_Hedgehog_...ase_Zone_Act_1
I need a code that'll allow the water level to be controlled by the 2nd controller I'm curious and would like to experiment with this and see how this could change the stage.

Hi Superrayman. I normally don't do music codes because they don't interest me very much, so will have to pass on your first request.

The second request is very interesting, but looks like it would require a ton of codes and a lot of time to get something like that working, so it would be a ROM hack rather than a few Game Genie codes. Although I might look at this later, will have to pass on it for now.

Hey Tony,

I was playing Haunting for Mega Drive with some of your Game Genie codes. When you run out of ecto, you are sent to the dungeon area where you can resupply. You are also sent to this area after completing each house. I noticed I didn't have to gather anything - the area insta-completed upon starting and the ecto would be replenished. I was using these codes:
- RH2B-86T2 master code (Tony)
- AM2A-AA9W infinite health (VisitntX)
- AM1A-AA4J infinite ecto (Fanat)
- 9V9A-DCC6 infinite spells 1-3 (Tony)
- 579A-CAC8 infinite spells 2-3 (Tony)
- B39A-C9MA infinite spells 3-3 (Tony)

Initially I figured the area auto-completed because I had enough ecto, but no, having only the ecto code on still makes you play the dungeon area. As far as I can tell, it's your 3-code set for the spells that effectively skips the area. Which is very welcome in my opinion :) I tested this by running out of ecto as well as completing a house, in both cases I didn't have to suffer through the dungeon area. I wasn't sure you were aware of this, as I can't remember when you made these codes and if I tested them. So just in case you want to update your notes :)

Hi GelmiR, good to hear from you. Was not aware of that, so will add new notes to that code. Thanks for the info.

I remember the first time I played that game, I had no idea what was going on. Once you figure things out, kind of a fun game.

EDIT: Code description has been updated on GH dot org and The Code Hut..

Likewise :) Good call, I think it's a very useful side-effect of the codes - seeing as it skips the most annoying parts of the game.
I agree, it can be a lot of fun! Though I mostly enjoy it in short doses.

edit: Youre welcome :)

Radical Rex (Genesis) Game Genie


A0XT-2AHA
Start a new game with 5 continues (instead of 1).

ALYT-2A7N
Infinite continues.

I'm hoping to explore what happens when you trick the system into running in 448i / 480i mode while playing a Mega CD game. Could we make a Game Genie code to do that? (This is part of a longer and more ambitious project.)

Hey Tony, what's up?

I'm replaying Terminator 2 Judgment Day and picked up some things as I was going through. The game keeps track of your damage, accuracy and efficiency.
Damage is not the damage the player character has sustained, but the damage that is done to the environment in the current level.
Accuracy pretty much only registers if your shots hit anything. If every shot hits either an enemy or object (that subsequently usually explodes), you will always reach 100% at the end of the level.
Efficiency, I'm not sure how this works. But from what I've seen, I suspect it slowly starts to count down after about 3 minutes. I've reached 100% for a level several times by keeping under 3 minutes or so.

During gameplay, the only stats displayed are the player status (health) and rounds (ammo). Though in the second-to-last level, Cyberdyne, damage is also displayed among the stats. This due to having to do a certain amount of damage in the level before being able to place explosives to finish the job.
As it seems to be possible for the game to display stats other than health and rounds, do you think it would be possible to display damage in all levels with a code? And/or maybe accuracy and efficiency?

Another thing I'm interested in is if collision for the driving levels could be disabled for terrain as well (you already made a code for the vehicles). This would be for exploring and mapping.

Final thing for the lulz, I wonder if the intro where Arnie arrives could be made playable :D I think most intro/demo things in these older games is actually recorded input that can be altered?

None of these would be essential codes, and you pretty much already covered Terminator 2 Judgment Day. So no worries if you'd rather pass :) If needed, I can provide a save for the only level that does display damage. In any case, thanks for reading!

I've never heard of tricking the Mega CD into running in 448i / 480i mode. Is there any info on this?

Most of that sounds interesting. Would appreciate a save state for that level with the extra damage display, preferably just as the previous level is ending. Finishing up my current project, so can take a look at it in a few days.

Hey Tony, I sent the saves to your e-mail :)

Save 0 - The intro
Never really noticed before that in the intro, the status (health) and rounds stats are displayed as well.

Save 1 - From John's house to the mall
Unpause and walk right to start the driving section (motorcycle).

Save 2 - Dyson's house to Cyberdyne
Unpause and walk left to start the driving section (police car). This is the level before Cyberdyne.

Save 3 - On the road to Cyberdyne
This is while still on the road, seconds before starting Cyberdyne. Unpause to end the driving section and start the level.

Save 4 - Placing the tnt in Cyberdyne
Unpause the game and walk slightly to the left to get a prompt to place the tnt During the level, you have to cause 70% damage to the building. After having done this, a message will pop up that the structure has been weakened enough to place the tnt. Once it is placed, the damage stat will be replace by a timer. This is the only time in the game a timer is ever used.
It occurred to me that if we do get the damage stat in all levels, it might then be connected to having to do 70% damage and placing tnt as well. If that'd happen, it would probably not be possible to complete any level. Remember how weird this game's programming was?

Save 5 - Cyberdyne to the steel mill
Unpause the game and walk left to end the level and start the driving section (SWAT van) to the steel mill, which is the final level.

Some other notes:
- I can pretty much confirm that the efficiency stat only has to do with how quickly a level is completed, it doesn't matter how shot up the player character gets. I got about 80% efficiency at Enrique's compound level after completing it in less than a minute (very small level). In that time I grab the tnt, minigun, and some ammo. I tried again and only got the tnt, finishing the level in less than 30 seconds. I then got 100% efficiency. So for this small level, they radically toned down the timer, it seems. Edit2: I was wrong - it's not just time. Missing a whole bunch of shots greatly decreases efficiency as well. So haven't figured it out yet.
- There are no health codes for John and Sarah Connor. I don't need them, and with this game's programming, they'd probably each need about 5 codes to get invincibility. But the player can heal them (I forgot about this) at the expense of their own health. When having invincibility codes active, the player's health doesn't go down when healing either John or Sarah, and they can be fully healed. What didn't make sense to me, though is that I just tried it and John still died - while he was off-screen. As far as I know, this never happens in the game. If you disable their follow status and leave them somewhere, they never get hurt when the player isn't around. Must be a side-effect of one or more codes. I'll test it some more later. Edit3: I was sort of able to repeat it in the same level. John didn't die, but his health was greatly decreased while off-screen. Not sure yet why, though. Even when on-screen, enemies do not attack him.

Thanks for looking into it, let me know if you need anything else :) Cheers!

Edit1: forgot to mention I sent you the files by e-mail.

I got the email, thanks! Will take a look at this in a few days.

Thanks in advance :)

GelmiR, I started working on the T2 game and have made a little progress. If you pause and un-pause the game with the following code turned on, the extra Damage stat appears. I've only tried in on the first level, and at Dyson's house. I'm not sure if it's functional or not. If it's not functional, it may require more codes for that. Will also require more codes to have it displayed all the time.

Terminator 2 Judgment Day (Genesis) Raw Game Genie

8904:6002
Pause and un-pause the game to see the extra damage stat.

Sounds cool! :) Though unfortunately I can't use Raw codes on Wii. Would you like me to test it with Gens first, or can I convert it to Game Genie? I tried to download your converter from Gamehacking, but don't haven an account there.

You can get the converter from my site without any account, but here is the converted Game Genie code: ALET-AA2E

Found it, thanks :) Turns out I already found it before, but couldn't figure it out. I didn't know you had to put additional zeroes in front of the raw code. So next time I can convert it myself :) Thanks for the code, will test it now!

Tried the code, but it has to be 'reactivated' each time you enter a different area. Also, I can't really tell the logic in how it counts damage yet. Sometimes I think it resets and it doesn't update damage 'live'. I've completed levels with about 20% damage listed on the top left, but the end-level-screen listed the correct 100% :) With this game, though - I wouldn't bother if you think it needs 5-6 codes for it to work.

In T2, it determines if it's going to show that extra damage stat in part by checking to see if the current level is level 0x0C (12). It numbers the levels a little differently than what you'd expect. There are a ton of checks to see what level it's currently on, and it looks like it will take at least a few codes to get the damage stat working correctly. May come back to this one later.

Thanks for trying and for the info Tony! But if this would require a bunch of codes, I wouldn't put more time into it :)
I've been in a Mega Drive mood for 2 weeks already, going to read back in this topic to see if I can find some codes I'd like to test.

Would require a lot of codes, so I've stopped working on it.

No worries Tony :) Thanks for looking into it!

Does anyone know if Robocop Verus Terminator PAL version has a code to run in 60hz with the correct music speed? RYGB-T6WA bypasses the region lockout but the music plays too fast.

I have a regional bypass tool that should work on this game, and will let you try the 3 different regions to see if you can get the music at the right speed.

You can get it from my site: https://codehut.gshi.org/Download.htm#RegionTool

Or from RHDN (with a full description): https://www.romhacking.net/utilities/1687/


EDIT: The program works on the USA version of that game, but I don't think I ever tested it on the European/PAL version. Should work though.

EDIT2: To clarify, the program should be able to bypass the region lockout, but I don't know if it can get the music playing at the correct speed. You'll need to test the 3 different regions to find out for sure.

This tools can be used (or adapted) also to patch japanese games (like Rent A Hero or Yu Yu Hakusho for example) so they will play with correct music speed on a 50Hz Pal console?

The program will work on Japanese, USA, and European ROMs, but I've never tested the program on that game, so don't know if it will work or not. The program won't work on every game since there are so many different ways of handling regions, but it seems to have pretty good compatibility.

Hey Tony,

I'm interested in doing some digging into The Pirates Of Dark Water. Did you ever finish playing the game? In any case, before I type up a (probably) looong paragraph I thought I'd check if you'd be interested.

The map screen shows a location that might have been a planned/cut level at some point. For now the only thing I'd be interested in is; would it be hard to check if the location has a selection slot like all the others (while you progress through the game) do? I doubt there's anything left (if there ever was), but it'd also give a name to that location. It may also have just been the starting location.

GelmiR, I've never finished the game. Your instinct on this type of stuff is usually pretty good, so I'd be happy to take a look.

Cool! :) Is there anything you need from me? I'm using the May 1994 rom. There's also a January 1994 rom, I'm curious if there's any easy way to determine if there's any differences between the two. I initially thought it was a minor revision, but it seems January is the US release and May the European one.

As for the map screen, at first I was interested in a level select that allows the player to pick any level at any time. But I don't see how the game would be able to determine which levels the player has already completed. Also, some of the location images change just prior to or after finishing its level. I suspect it'd require a ton of codes. And seeing as there's already a level select, doesn't sound like it's worth it.

The player has to gather a Magical Compass and the 6 Treasures of Rule. The map selection icon is the head of Ren, one of the main characters. It will always start on Pandawa Jungle, which is sort of a training level. After that:
- you can pick either The Citadel (Magical Compass) or The Port Of Pandawa (Treasure #1), which are levels 2 and 3. Both need to be completed.
- level 4 is Bobo Mountain (Treasure #2).
- level 5 is Janda Town (Treasure #3).
- another pick for levels 6 and 7 between Andorus (Treasure #4) and The Sunken Bridge (Treasure #5).
- level 8 is The Maelstrom (Treasure #6).
- level 9 is The Dark Dweller's Lair (Treasures are used here).

Level names are displayed in the banner on the bottom. The game feels complete to me when looking at boss/treasure placement as well as dialogue. Though I'm very curious of the unused/unmarked location. I wonder if it was either a planned/cut level or if it might be Octopon and thus, the starting location. If for example level 1 the Pandawa Jungle is cleared, the selection icon will still be on that location until the player makes a choice for the next level. If it was the starting point at some time, the location might have been used for only that. I wonder if it'd show us a name, though. Maybe they thought it was too confusing.

One thing I noticed in the level select that looked off to me, is that the Mantus boss (he appears in Andorus) is placed in Janda Town, giving it 2 bosses. They probably just messed up the order somehow, though. Let me know if you need anything else from me :) As always, thanks in advance!

GelmiR, do you have a Gens or Kega save state where all of the areas are accessible on the map? I'm assuming that each level becomes available on the map when you finish it? Thanks.

EDIT: Or does the level select do that?
EDIT2: I see that the level select doesn't give all access on the map.

No, not all levels become available after finishing them. After level 1, levels 2 and 3 become available. After that, only level 4 is available, etc. The level select doesn't give access to the map, right. It's also kind of confusing unless you are familiar with the game, I think. If you need it, I can 'translate' the level select names to the full level names.

One thing at a time, of course, but another thing I was wondering. In the level The Sunken Bridge you can obtain Ren's missing sword piece - something not covered in the cancelled animated series. There's also a password to start with the full sword from level 1, I think it was DSILLER. This doesn't neccessarily mean that the sword piece item is hidden somewhere away in level 1, right? The player starts the level with the item already obtained, the cutscene showing the mended sword plays the second the level starts.

Do you have a save state where any of the areas are accessible on the map?

IITBDIA is the first password you get. If you enter that from the options > password screen, you will go to the map. From there, you will see that Pandawa Jungle is still selected. From here you can first pick either The Citadel or The Port Of Pandawa. Hope this helps :) If you still need a save or whatever password, I'll be happy to provide.

That password should work, thanks.

You're welcome :)

I feel so stupid (and dumb!)... I was wrong with where the Sunken Bridge is on the map I provided for you...... the bridge appears and leads up to the area we are looking into (facepalm!!)
Sorry man, I hope you didn't put too much time into this yet! If you put in the password STOYODA, you'll be able to see it. I'm both relieved and disappointed nothing is missing.

GelmiR, it's all good. I didn't have very much time into it, but I figured out how to have a few of the areas on the map always available, so I may spend a little more time and just make a Game Genie code that lets you have access to the entire map from the very beginning of the game. Not sure if that could possibly break the game or the flow of the game, but the level select lets you start wherever you want, so I'm guessing it wouldn't hurt.

Thanks for getting back to me, that's a big relief :) And I've love to extensively test a code like that, I can't seem to get enough of the game at the moment :) Though I wonder if the game will sort of 'reset' itself after selecting and beating a level. Hope I'm wrong on that. In any case, I look forward to any testing.

I found these while working on the ZAMN editor, but forgot about them...
