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

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

Hi Amstrad.

Here is the patch for Carnage. You'll need to patch these two files:
CARNAGE.EXE 9.968 bytes
HARRY1.-0 17.680 bytes.

This game was a little hard to patch. It has multiple checks and I think it has 386 specific routines too.
Unfortunately it also run too slow on my Turbo XT.

Monkey Island 2 was also refusing to start on this machine: the ips patch allows it and it runs enough to be playable, which is fantastic!
I consequently tried to do the same for "Indiana Jones and the Fate of Atlantis": it is working now, even if a bit slow, still manageable.
You can find it as an attachment (it has to be applied on the international release 1.0 of Fate of Atlantis, tested on the 5x1.44M installation disks).

Is there other games like that (checking 286 as min requirement, but running well if removed)?

Hi, @GreatStone,
I tried your patch for "Indiana Jones and the Fate of Atlantis" floppy version 1.00 ("atlantis.exe" file from 1992.04.17, interpreter version 5.2.20) and it works fine on emulated 80186 CPU in DOSBox-X (probably NEC V20/V30 CPUs are fine too). But unfortunately this executable is incompatible with 8086/88 CPUs.

I also tried the CD-ROM version of the game (CD-ROM version 1.00, "atlantis.exe" file from 1993.05.05, interpreter version 5.5.00) and it's way better compared to the floppy version: it has digital speech, no CD-ROM checks and game protections by default and works on 80186 CPUs (probably NEC V20/V30 CPUs are fine too) without any patches. I patched CD-ROM version "atlantis.exe" to save/load gamesave-files in current install directory ("C:." instead of "C:\FATE") by default, but I can't make it to save scores-file "IQ_POINT" in current install directory instead of the drive root directory. Can someone help with this?

Thanks!

Only v1.0 runs on a 286, all later versions need a 386 to get in-game - they can navigate the menu fine, but will freeze when loading any map.
