Hi, @Gustavo!
Appreciate your effort in these 80286/80386 game patches for 8088/86 XT machines! But I have one note here. I think these IPS-format patches are not the best for distribution as they do not contain any information of original file to be patched - at least it's size. For example there are a couple of exe-file versions for some of the games you made IPS patches for - floppy versions, CD versions, different version with game bugfixes... Why don't you use something like PatchMaker instead?

Hi aVd!
I understand the limitations of IPS format you mentioned, but I think it's better to use IPS since it's almost a universal format for simple cheats and videogame hacks. Also IPS software is available for many platforms.

These are the versions I patched:
MONKEY2.EXE 110.811 bytes
wrath.exe 32.897
magic.exe 155.382 (needs to be UNP'd first - 446.215 bytes when UNPacked)

Hi,
Can you patch corridor 7 game?

Hi amstrad,
here is the IPS for Corridor 7 - Floppy disk version.
File: C7.EXE 201.444 bytes

Tested on 12 Mhz NEC V20. The game runs, but very slowly: 2.0 to 1.0 FPS.

HI Gustavo,
Thanx
Alien carnage/Halloween Harry need 286 CPU to run.

Thanks for the additional info, @Gustavo! I'll try these patches.
