The best option imo is to start using Virtual machines with the correct os on it. It's basically what was done with curse of monkey island, and hexen.<br>The thing is this solution may not be legal depending on your approach, and while it works in some instances this isn't a sure fire solution, but it sure as hell beats the painstaking and error-prone method of editing files.,(reply>), @Wally Hackenslacker PS4 emulation ia more straight forward than PS3. As computers gain processing power, PS4 and even 5 emulation is easier to do than with PS3 era games due to its unique infrastructural design.,(reply>), And it depends on the system. For older systems like the PS2 era back emulators are things of beauty, but for most consoles in the PS3 era onwards, emulators are still pretty much a work in progress. And age isn't even a guarantee, classic Macintosh emulators of the MacOS 7 to MacOS 9 era for example are still either very unreliable, very very slow, or both.,(reply>), 32 but vista days are a weird forgotten timeline. We are still in the infancy of discovering compatibility issues with this, Xbox and Xbox 360 era, etc,(reply>), @Gunsong1 tbf scummVM technically isn't an emulator, moreso a reimplementation and your implication was using something akin to dosbox or virtualbox. Despite that though, you gave 2 very poor examples: Curse of monkey Island is of course playable via scummVM and Hexen uses a version of one of the most widely source ported engines ever made (idtech aka the doom engine) and could be easily played natively with chocolate hexen or GZdoom with just its WAD file. I don't doubt that there are game's that may need to be played via the use of system virtualization though.,(reply>), @mabalito what do you think VM stands for in scummVM? :)
