so bad luck because all is for the resident evil 1.5.
maybe you know ,it's said that the re1.5 only be finished for 80% or ??%.
if that guy release , we can repaire it by psx debugger maybe!
so bad luck.....

Regurgitated to make sense

Attempt a character modifier, it's the wrong address but it kinda works
, I know it's the wrong address because it doesn't change the profile picture or attacked sounds from Leon.

Character
300A1FAC 00xx

00 = Leon

0E = Ada
When you start the game Ada doesn't have any weapon equipped so you have to do it manually off the inventory.
The Knife turns into Handgun when equipped that Leon holds sideways whilst in his alternative costume, if you uni-equip the knife then equip the handgun, the handgun will turn into the calico950 also the game goes into a strange inescapable walking animation loop when Kendo has finished talking in the gunshop.

0F = Sherry
Doesn't crash the game but instead just loads Leon's model & texture as normal

A few years ago, when I was on Bioflames (and Bioflames was a little more active), I got inspired by Mark Grass to learn how to make GameShark codes for the PlayStation Resident Evil games, and I made some interesting codes. I was able to make large pools of blood underneath the zombies in RE1, take away items/weapons/health from areas in RE3 to make it harder, removed the white fade that happens when you die to see an extended death scene, and I was able to lock the camera angles, plus other things too.

[kevstah2004]

You wouldn't happen to be Rockman at bioflames would you?
if you still have the codes care to share them or give pointers to how you made them.
I tend to share whatever I find no matter how mediocre.

[MeganGrass]

I'm wondering the same...

I got inspired by Mark Grass

Heh, it's really nice to know that I have given people inspiration.


Ah, things were so different back when BioFlames was active... no canonicity or administrative/moderation nazis, Jill fanboys had yet to join an alliance, people were interested such discoveries (GS codes, beta material, etc), and most of all, I wasn't unrightfully discredited in this community.[/off-topic-nostalgia-rant]

[kevstah2004]

I was looking forward to the other things he'd found but he didn't post anything up after these

Character Posed Position (Kneeling down, laying down, standing up, try random values!)
First Zombie Has Infinite Health
Alternate Death Sequences (try random values! Lower values, which include 00, remove the white fade!)
No White Fade

If it is him, I hope he doesn't mind as recently I posted his codes to share at http://www.thegshi.org/vb/forums/11-...-Retro-Hacking

[RetroRain]

No I don't mind. Yes, I am Rockman from Bioflames, but I thought you guys knew that.

I don't have any GS codes currently. I gave up on it because everyone was big into the PC modding, and I really didn't think anyone was interested in GS codes anymore, but I do remember how I made those codes, so it wouldn't be hard for me to get them again. I remember some of the codes I posted in the past were obsolete.

If I have some free time, I might see if I can do some code searching, and yes I will release the codes if you want them.

A little be good if you could get him or her to register over here though better than me trying to fill in the gaps with Google / babelfish.

I just found about about this project by accident after looking for that BH2 Trial for its XAS files. Awesome hack!

I apologize if this wasn't obvious enough, but what exactly are you all using to get the AR / Game Shark codes to work on the emulator? Also, what is a good hex editor to use for hacking PS1 games on said emulator? I'm a noob at this.

I'm using the latest ePSXe emulator.

Also, how are some you able to figure out what works in the game code-wise?

You should be able to use an add-on known as "PEC" (PSX Emulation Cheater) (within the emulator settings, select it for the graphics/audio, then use your normal settings within the set-up menu for it).

I think you could use really any general hex editor for it (of course, just taking a guess at that).

How I can edit the psx iso without break it??

[Upaluppa]

How I can edit the psx iso without break it??

You could try using CDMage!
It's one of the few image editing tools I know of which do not break PSX ISO's.
I don't know of an official site where you can download it, but you should be able to find the program with the help of google.
