Everdrive-MD Flash Cart

just got myself a official JP copy of, Wolfchild
for the mega cd, and it won't load

I wounder if there could be an update
for the multi-bios?

also, it would be great to see in a future update
having bios to load the correct screen with its
corresponding region, if thats even possible

What kind of luck are folks having with the region-free Mega CD BIOS on Krikzz's site? My happy comments upthread were probably premature, as not everything seems to work. Here's what I've found so far on my Model 2 Genesis and Model 2 Sega CD, both NTSC-U.

Annet Futatabi, Earnest Evans - work perfectly with region-free BIOS (won't boot without it)
Sengoku Denshou, WonderMega Collection - crash at the BIOS screen

However, these aren't originals (ahem), so maybe something else is going on with SD and WMC. I might try using ConvSCD to see if that helps. Anyone tried these with originals?

BTW there's a lot of flickering at the top of the BIOS screen. Some sort of timing issue? Is the region-free BIOS based on PAL code or something?

[cleeg]

I found there was flicker at the top of the Euro BIOS when it was run at 60Hz speed on my PAL MCD (Multi BIOS chip modded), this may be unrelated but hope it helps.

krikzz, do you accept payment through debit card? does the everdrive have ym2413 support? if not, can you add one? what is the max. rom size accepted? Thanks

payment only via distributors which published on my website. so check which methods they accept.

Ah, maybe it is the Everdrive which doesn't properly understand the combo of Genesis 1 and Sega CD 1, then. Krikzz??

probably you have old firmware. bios loading works fine on any system only on carts with firmware v12 or more new

for all who can't run some game on mega cd:
cart just change bios to some hacked version and this allow you to start game. hacked bios not check cd region, so allow you to run any region, original bios check region and if CD not from same region as CD unit, then system will stay on bios screen or cd player will be started.
BUT any bios can't help if game do region check by self or physycally cant work on sytems from other region
also i recommended to try some various versions of hacked bios, i put one on my website, but that is not mean that it is sole version in all over the world

would you add a ym2413 by request? and which is the max. size of roms?

[goldenband]

Thanks very much to folks who've weighed in, and to Krikzz for being so willing to help. It certainly wouldn't surprise me if WonderMega Collection had some way of checking whether it's running on an X'Eye. Sounds like it might be a good idea to start a thread finding out which Mega/Sega CD games do their own region check?

[villahed94]

too many pages. Can you recommend me one(the best and cheapest)? Also how much would cost me the shipping to oaxaca,mexico?

[KRIKzz]

to villahed94:
to many? just 4.
shipping some near to 4-5usd
sorry, but how can i add ym2413 by request? make holes in pcb by finger and solder on chip? of course i cant put ym2413 by request
max rom size 5mb

[Chilly Willy]

sorry, but how can i add ym2413 by request? make holes in pcb by finger and solder on chip?

THAT would be fun to see.

max rom size 5mb

I think you mean MB, 5 milibits would not hold even one game.

[KRIKzz]

yes, i mean 5MByte

Any follow up for the ETA on DSP-1 support on the SED?

[elcheapouno]

tried cd-2-u.bin and had no results.
if im to play JP mega cd games,
do I need a hack JP bios?

the multi-bios works with finale fight,
but not wolfchild..

payment only via distributors which published on my website. so check which methods they accept.

jp games is ntsc? if so, then you should use U bios, if not, then you should use E bios.
if you see some like "this game developed only for ntsc systems" then bios loading can't help, because game checks console region also (main console region, not CD unit region)
i want repeat that bios swap abble to help pass region check on bios level, and bios swap can't help to pass region check on game level (if game checks main system region)

if you can see screen with sonic and sega logo on black background, then region checks on bios level is passed, so if you have some trubles after this moment, then none of the bios will not help you.

i tired talk about bios loading (: may be somebody who has good english can explain tricks with bios better. i think that bios swapping features is same for everdrive, megacart and neo myth, so you can read some threads about this carts+bios loading


to Lastcallhall: in next few months will be available Severdrive with empty place for DSP1. stoneagegamer probably will be sell carts with preinstalled DSP1 as option

[villahed94]

Does retrogate have stock of your everdrive? because it doesn´t say anything.

A quick question about the Super Everdrive: I saw that the pcb will fit a US SNES cart, but will it fin inside of a Japanese Super Famicom cart?
