the checksum of bios

[mych]

Does DC bios checksum itself when DC boot up ?
I got a DC-DEV bios file,and translate it japanese to Chinese.
To test it in emu,work well.
But when i flash it to mx29lv160, DC blackscreen a moment then freeze at logo.
if the checksum be sure,how to skip it ?
BTW: i have try to repair CRC32 to bios origine ,freeze too.

Original dev bios not work normally on DC. You need a hacked dev bios.
In DreamShell hacked dev bios is here - /shared/bios1_011_01_hacked.bios

the origine dev-bios that i got could work on dc well.
but i change it's some words, be freeze.
today i have try 1_011_01_hacked.bios on dc,it could work well too.
but when i translate it....freeze too
so i wonder ,maybe bios booting up, have a check to itself.
dear swat, may i have your email address? so i could send the Chinese dev_bios to you.

I found the dc bios included russian font, but i couldnot call them out. so ,i need a game exe file to learn calling code. maybe i could make bios show Russian Message.

[SWAT]

In Russia DC games are not translated official, it makes the pirates. I do not think you'll find there link to the bios.
Unfortunately I do not have to hand the game. Wait a little,You will get it from anyone else.

Люди дайте пожалуйста ему кто нибудь 1st_read от русской игры.

[alex]

[mych]

there are two way that DC game to show Russian.
1. direct calling out bios inside fonts
2. game inculded a single fonts inside some file
