Hi there,
I wonder what a GTA 1 style game would be like for the megadrive? GTA was on the gameboy color and though it wasnt great it was a proof of concept. Driver on the GBC was much better and I really enjoyed that. My favourate GTA is actually the version on the GBA.

I wonder how well the mega drive would cope with this? Watermelon im sure said somewhere that they have managed to increase the number of sprites on screen. (i may be wrong on this) This would mean that it would be possible to have more cars and pedestrians on the roads.

What are your thoughts on this. I dont know much about the technical limitations of the MD so anyone with that knowledge would be much welcomed with their thoughts.

Anything is possible, get to it.

You could have sprite scaling, which gta1 uses I believe.

If a GBC can handle it, then why the Mega Drive can't do the same?

Yup, strip enough stuff away and it'll run on most anything. The concept is fairly simple.

Personally yes, it can be done on the Mega Drive but it really depends whether you want a port of GTA1 or a GTA styled game like Retro City Rampage.

If it is the former, from the looks of things GTA1 doesn't really feel like a PS1 game with probably the redbook audio, more buttons, larger palette, FMV (I think GTA1 did have FMV for cutscenes) and the scaling being the only big things that the Genesis doesn't have (well the scaling could be done software scaling or lots of ROM space but the maps are quite big and there is the 6 button controller). It would probably be in between the GBC version [that despite being impressive had bad controls] and the PS1 version in terms of capability. Since the Genesis has a higher resolution than the GBC, it would display more of the screen but less than the PS1/PC versions that I believe are 640x480 so probably the HUD would be smaller and the phone text during the missions might have to be split up for readablility reasons. As for traffic, maybe one or two less cars on the road than the PS1 version to reduce slowdown. Due to that the radio is a part of GTA and to even have a radio would rely on impressive work in terms of voice samples and music, it would have to be mostly different music (stuff like Head Radio, the Hip-hop, the country/western and the Rock stations would have to be cut due to heavy use of voices but the techno and the Dance stations would survive and the funk station just needs to do it instrumentally). Controls would have to be simplified (something that the GBC version did not do, you have to press 2 buttons to get in your car) but with the 6 button controller, the gameplay would be more closer and easier to play. Palette wise, since from what I can recall from GTA1 is a lot of yellow and grey with blue for the sea and green for the grass, the floor and buildings might be able to use one palette leaving room for the player and the other cars (that were multicolour if I remember like blue, pink, red) to choose from 3 palettes.

The Sega CD would be a more closer port due to the redbook audio for the radio, FMV cutscenes and scaling. Imagine the PS1 version with a smaller palette, maybe longer loading times and a smaller resolution and that would pretty much be what GTA on the Mega CD would be like. 32X would have a larger palette and able to scale more closer to the PS1 version but all the other limitations from the Genesis would be there. 32x CD versions would be even more closer with just the resolution difference and the Saturn version would be just like the PS1 version maybe with faster loading if the RAM cart was used (who knows maybe even closer to the original PC version).

If it is the latter then only your imagination would be your limits since you can build the game around the console instead of taking something that is already there and downsized it.

A regular 32 megabit cartirdge could hold the game without radiostations or any kind of pcm music.

GTA was in development for the Saturn but canceled because they didn't have enough money to make it onthat many platforms.
