TaxAkla: Yes, your exe has problems with GOG version:
1) Has longer loading times (about 1 minute or more) and the letters in the menu are all crossed in red.
2) I remember you exe replace the animated menu (bik video) for the earlier one, so isn't a bug per se.
3) I tested with the mod AVP Classic Redux (
http://www.moddb.com/mods/aliens-versus-predator-classic-redux). Some problems are: the Marine night view isn't clear like the AVP GOG and it has the same problem with crashing when the level is finished. It will be cool if we could play the campaign with the mod without crash.
TaxAkla, I don't know if the "exe" you're talking about is MelPyth or AvPx. It would help if you clarified. As far as I understand, sirlemonhead was a part of both projects. For the rest of this post, I'm going to assume you're talking about AvPx, the executable that allows Gold Edition to work properly on Windows 7 (MelPyth is a mod that changes a number of core features with the gameplay but it unfortunately won't load levels on my computer).
I have zero clue as to why you're talking about the exe having problems with the GOG version of Classic 2000. AvPx was made years before that stolen version was released on GOG, and even Steam for that matter. As far as I understand, it was designed to be installed on top of AVP Gold Edition. Even the default install pathway is Fox/Aliens versus Predator, not GOG Games/Aliens versus Predator Classic or Steam/SteamApps/common/Aliens versus Predator Classic. I don't have the faintest idea why you'd even want to run AvPx through the Classic 2000 folder because Gold Edition is the superior version, aside from not having Gold Edition (which kind of makes AvPx a moot point, no?) or the fact that you can't feasibly do multiplayer in GE anymore.
Same thing with Redux mod; that mod was designed to work
specifically for Classic 2000. If you want to play the Redux version, why not just use Classic 2000? I mean, if you want to play the classic Gold Edition version, play that version, don't add stuff on top of it. As of right now, it sounds like you're running AvPx on top of Classic 2000 on top of the Redux mod. Of course there are going to be problems with it if you do that, but they don't need fixing. The Redux mod was solely the work of Mad_Max_RW and it's neither sirlemonhead's nor Max's responsibility to ensure that the two are compatible.
