Resident Evil: Code Veronica - Debug Menu [DC]

[VincentNL]

Taking a little break from RAH, I'm back into hacking hidden debug modes of our beloved Dreamcast / Naomi games!
Let's start with one of the best games ever made for SEGA Dreamcast and probably the whole Resident Evil franchise: Code Veronica!

It's currently being tested by @Esppiral, if no major issue reported, I'll post the patch soon!

After loading .cht file or patching Track3.bin , once in game, press L+A to bring up Debug Menu.

Please note that STAGE,ROOM,CASE correspond to the physical .rdx filename on disc.
For example, if I want to load room with filename R0_3091.rdx:

`3` = STAGE value
`09` = ROOM value
`1` = CASE value

Special thanks to Esppiral for testing!

Excellent work, my friend! Keep it up.

@yzb has done a first person view mod, but there IS an issue...
Do you think you Can achieve it ?

[Dirge Of Ram]

Battle Clothes Damage, Random Enemies and real Zombie Decapitations would be nice to have on that debug menu. I'll take the longer loading times just to fight more Zombies in each rooms. Give Claire the Sub Machine Guns & new Costumes, need more then just First Person Camera view!

Code Veronica doesn't need a remake doesn't need to "get with the times". No Alyson Court even the Hivemind today can't cope with dated gameplay & backtracking. Leave this classic alone!

First post updated, you can choose to enable it in two ways:

A: Download .cht cheat file (Flycast / Retroarch Flycast core)
B: Manually patch your Track3.bin

Thanks for the patch, check out the release version Evil Twin: Cyprien's Chronicles.

[qwerty4]

this looks great, thanks for all the hard work :3

VincentNL the button combination - L+A was invented by you or it was left by the game developers.

[VincentNL]

No, my code only creates a bridge-function to execute debug menu from pause.

Thanks very much ! Works like a charm. Do you know what CASE, MUTEKI, SYUKAN, and JIMAKU do ?
