Scripting and Reverse Engineering / Assemble source code

« on: 2005-11-17 14:51:16 »

I managed to dissasemble the FF7 executable ("only" 105 MB or so) and now I'd like to re-assemble it. Would anyone be able to walk me through it?

So far I've just tried masm32 version 8 but it don't want to do it.
ff7n.asm(60) : error A2085: instruction or register not accepted in current CPU mode
ff7n.asm(66) : error A2066: incompatible CPU mode and segment size
ff7n.asm(69) : error A2085: instruction or register not accepted in current CPU mode
....
ff7n.asm(217) : fatal error A1012: error count exceeds 100; stopping assembly

Troubleshooting / FF7 rendering idea

« on: 2003-08-15 08:35:44 »

I've got this great idea to improve the graphical performance of FF7. Unfortunately I do not possess to skills required to do this.

Basically "we" are writing an OpenGL wrapper and a GLUT wrapper, and improving it to fix known issues.

Some of the features would be. (All features should be optional and fully configurable)
Some have complained about the speed at which the motorcycle game runs at (I get that problem too). So to combat that we enable a delay on the calls to bring the game to an acceptable speed.

Then anti-aliasing would be good to implement.

Support for more resolutions would be neat.

Hehe, 6x anti-aliasing in 1280*1024, ought to look good.

The functions FF7 imports are:
[opengl32.dll]
glAlphaFunc
glBegin
glBindTexture
glBlendFunc
glCallList
glClear
glClearColor
glClearDepth
glColor4ub
glColorMask

Archive / FF7 3d performance

« on: 2003-08-08 12:05:41 »

I decided to upgrade to the newest release of DirectX and video drivers for my Radeon 9700 graphics card. Following this change FF7 took a deep dip in 3D performance, mainly during battles, 2D scenes still render like a rocket, while 3D battles renders like if I was running it through slowdown.

I've tried the DX uninstallation tool and reverting to the old drivers, but it is still the same.

1GB RAM, 2 GHZ, and windows XP with DX 9.0b and Catalyst drivers 3.2 and 3.6 (I've tried both)
