Doom Inf. Heath GG Result

[ugetab]

I found an emulator that logs SuperFX code, so I decided to finally get rid of any doubt about never having a directly-enabled Infinite Health Game Genie code for Doom.

This is the logged SuperFX code, with it reducing the health value in SRAM:
00:e834 40 ldw (r0) r0=$0058 SRAM=00:5AAE
00:e835 64 sub r4 r0=$0055 CY=1

Converted to PAR / Game Genie style:
00E83501

DF37-DF04

The GG code won't work, even though the address is effective.

In the file, if you go to 6835 in a rom without the header, you'll end up in the middle of the bytes 51 40 64 0A 02. Change the 64 you land on to 01. If the bytes you end up on are 4D 50 55 54 45, then instead go to 6A35, and you should be where I mentioned.

If you play the game from that modified copy, you should have infinite health.

Now, there's really no reason for me to attack this game any further looking for Game Genie codes to directly kill the health write routine. It'll only comply with some rough treatment of the code.

Here's a decent alternative:
6ED0-B57F
C3D0-B55F
9CD0-B58F
5DD0-B5EF

Finally, here's an actual, working Infinite Health address code, which will work in an emulator, at least:
705AAEC8

(GG: A69C-BE64 - It's outside of normal ram, but I have no clue if it would work because of this)

when i use the
6ED0 B57F
C3D0 B55F
9CD0 B58F
5DD0 B5EF

code for the SNES game genie it does give me infinite health but the enemies dont move and i die instantly if i collect any first aid health packs on accident. any way around that?

[Helder]

did you try the other code right below that one? A69C-BE64

Took a bit of doing, but I believe I found some redundant code to use as an alternative. Emulators don't have the quirks of hardware, and such info isn't quite forthcoming. Try it on the hardware, and I hope it works.

Edit:
Another small code. This shouldn't suffer from the issues of the Health code, since it's not replacing anything different in code.

yeah helder i tried that code too and it didnt work at all, but the new code;

6EDE 955D
C3DE 958D
9CDE 95ED
5DDD B07D
6DDD B05D

works perfect. the health counter flashes random numbers very quickly during gameplay and your little face at the bottom of the screen gets bloody but the counter never reaches 000 and i havent died yet.

It's stuck at 199 in emulators, because they don't need to do all the little niggling things that the console version actually does to succeed. The numbers you're seeing are related to screen refresh timing. I'm quite glad to know this one works on the real thing.
