MD Everdrive - Official "game doesn't work" Thread

[lost69]

Darxide has a region lock for PAL-only systems. You've got to have a 50/60hz switch modded into your console to get it to work. There may exist hex edit values or Game Genie codes you could use to override the country protection but I've not seen them.

Lost69, get a verified good working image [!] from a set. You haven't mentioned what your hardware setup is, anything about your Everdrive (OS, FW, etc), or anything about the file you're using. Chances are if you were a bit more detailed about what's going on then people could help you.

golden axe 2 good gen rom set 3.0 os29 firm13 my thing is they lay out of they of Controller set up is is weird i am useing a six button you cant move any thing with they Dpad

[Prodigal Gun]

Darxide is easy - just change the "A" in the rom header to a "U" for US systems. Changing it to an "F" should make it playable by any system. You can use any hex editor to do that. This is a Direct Quote from Chilly Willy at the following forum.

Lost69, you can't use a 6 button pad on Golden Axe II.

You either have to use a 3 button pad, or hold the MODE button in on your 6 button controller when powering on the game to get it to work.

I tried OS v23 with King Colossus and the game freezes everytime I try to save, patched or not patched rom... Back to OS v28 the game does not freeze and does not save...
Duke Nukem 3D does not save ("Backup ram error") with any OS I've tried...
Really don't know what to do...

Firmware v13
PC2.4

[Pannolino]

it's not like an official game which doesn't work but the translation of Fushigi no Umi No Nadia doesn't boot up (black screen)

could anyone try that translation or have any idea on how to get it work?

the rom go up to 1,5mb once patched btw so could be an header issue or something like that regarding the size etc?

[Eke]

A new patch has been released that fixes lockout issues on real hardware and accurate emulators, check that thread:

thanks, i'll check it asap

Has anyone managed to play the earlier revisions of Revenge of Shinobi on their Everdrive? They refuse to work for me.

[YAGRS]

I actually ran into this issue over the weekend as well. I tried to load both versions of Revenge of Shinobi I have on my SD card, but for both games, all that I got was a black screen.

I'm not sure if this is an OS 29 issue or not. I can't remember if I tried to load the games with earlier OS versions.

*Update*

Now I have no problems running Revenge of Shinobi. I'm not sure what the previous issue was, but it is apparently gone now.

[TEOL]

They're a straight binary dump, so they'll work.

Thanks for telling us about the No-Intro working. I'm probably going to go for it as I have 3 SD cards now.

A cross mix between GoodGen, No-Intro and Non-Good Gen for the full set.

And to the guys saying Phantasy Star 2 doesn't work. Yes it does because I played it before. You have to press the reset button when it's loaded it then runs perfectly.

Starflight ROM does not save, looked all over the internet and there is no existing hack. I read on Sega-16 (http://www.sega-16.com/forum/showthr...-It-True/page3) that Starflight uses EEPROM, so it makes sense why it wouldn't work. Can anyone point me in a direction to performing the EEPROM to SRAM hack myself? I'm comfortable with hex editing and ASM, but I need a little direction.

Thanks

Nope, this game does not use EEPROM, it uses traditional SRAM mapped between $200001 and $203FFF (odd address only) but, like many EA games, is missing correct ROM header to indicate it uses SRAM, which Everdrive OS is relying on.

Try patching the following byte sequence from ROM address $1B0 to $1BB, this will fix the header to tell the game is using SRAM:

52 41 f8 20 00 20 00 01 00 20 3f ff

[stereochris]

i will definitely try that and reply here when i get it working / if it doesnt work. Thanks for the info

[HANGAR]

Is there any way at all to get the Micro Machines games to save yet?

Doesn't work for me. After altering values the screen stays black...:rolleyes:

Micro Machines games use EEPROM so no, there isn't any way actually

strange, I'll have a look but changing the ROM header should not broke the ROM. Make you sure you properly changed the few bytes and did not simply inserted them, I know a few hex editors that insert bytes by default.

That was also my first suspicion. Accidentally used insert mode instead overwrite. But no, i used overwrite at the exact hex address...

[Eke]

There is indeed an additional checksum verification, which includes part of the ROM header.

Add this patch and it should work:

Is there any NBA JAM TE rom for 32X that uses SRAM instead EEPROM? Does anybody know how to change that? I know the Genesis version has a patched version that works fine, but I do not know if it saves.

Another question, the only known rom for Fifa Soccer '96 for 32X (at least by me) does not have any save settings in the header. I've read something about the final product being a late beta released because of the 32X market failure (Segabase). Does it have a saving feature in the real cartridge? And what about the password codes, I did not get any code while playing the game. This one just by curiosity.
