@Mitsurugi-w ping @pzlate I think his version may work with CF as well.
Confirm.I had asked Darksoft to look at this because I was trying to fix a Crazy Taxi at an arcade by replacing the broken GD Rom drive with a CF kit. It always freezes shortly after booting but if I recall correctly it worked fine if netbooted. I may be wrong about that. I never got it fixed before I moved.
sorry, no clear ideas why this happen.Hopefully someone will be able to fix the CF boot version at some point.
I know this And it's very useful.My repository is initially based on Neo-Arcadia old page since I'm French. I've just added some stuffs (Draksoft versions, converts 512Mo/1G, games I've patched...). I've created this repository to share games for preservation since Neo-Arcadia page is broken.
Is it really just you after midnight with a cape and plastic fangs?omg! I got a copycat called draksoft. Now I feel the pressure....

Is there any tutorial on hacking rom? I have been working on this for a week, don't have any progress.@KoshiroKazuma VF4FT game tries to talk with DIMM and determine it's firmware version, it won't work if firmware is less than 3.17, so yes, this game require hacking.
on the bright side - changes will be in very start of rom board space, it might be resolved adding IC7 EEPROM with hacked code, so no soldering will be required.
Thanks for you help.@KoshiroKazuma you may try to patch VF4FT (rev F) like this:
offset oldval newval
000205C6: 0B 09
000205C7: 40 00
000205D0: 0B 09
000205D1: 41 00
but I'm not sure if it will solve all problems
Sorry for my misunderstanding in previous post. I burned a patched 27C322 and inserted in IC7 socket. The game works!! It's awesome!!in such case it more looks like you have soldering problem.
when game tries to load some files from game "data" area it gets unexpected data and hangs.
this happen before DIMM board firmware version check, which is disabled by patch above.
I'd recommend to fill checksum area in ROM header structure, this will help you to determine which ROMs read bad.
brains + IDA Pro disassemblerhow do you find which bits in the rom should be modified ? Is there any tool recommend?
