So wine can let you run old delphi-based GM 8.1 games, correct? Are there any exceptions in what it can and can't do on linux regarding GM 8.1 exes? Also I realize in order to run my games on Linux without any Wine or external installer and actually "convert" the windows exe to a legit standalone Linux app, I need to buy crossover which basically is wine based but fills in the gaps to make it standalone / no need for terminal commands or 3rd party installs, just double click and run it by itself.
Is all of this correct? I want to know a few things before I go through the trouble of porting my projects downgraded from GMS to 8.1 AND purchase crossover. I would post this at the crossover and/or wine forums but this is specifically about porting GM 8.1 games.
No, it's not correct, the main difference between wine and crossover (other than the price) is the number of windows applications it allows you to "install" on linux and that on crossover some actually work better or just do work; while on wine those same apps won't work correctly or at all.
Crossover is based on wine, it's a compatybility layer, it installs certaing things that allow certain apps to work under linux.
None of them: wine, crossover, playonlinux converts anything, if it were possible linux would be the number one system on the world (by user number).
Among the things I'm currently doing is porting some delphi apps to linux, using lazarus and, in some cases, a lot of hard work.
Your best bet would be to install enigma on linux and port from GayMaker to enigma and then build.
