Guides on emulating older games

Aleph One (formerly known as the Marathon Open Source Project) is a free and open-source first-person shooter engine based on the source code of Bungie Studios' Marathon 2: Durandal.

The project commenced in early 2000, when Bungie released the code shortly before being acquired by Microsoft and spurred the fan community to further develop it. Since that time, Aleph One has become a successful project in terms of development and community support. Most modern-day and die-hard Marathon enthusiasts use Aleph One due to its enhancements over the original games and the fact that it is playable with today's platforms. Its name is taken from the second infinite cardinal number in transfinite arithmetic and references Marathon Infinity, the final game in the Marathon Trilogy (the "smallest" infinity is aleph-naught, or aleph zero).

Initially, Aleph One was only compatible with Classic Mac OS (even though a version of Marathon 2 had been previously produced for Windows 95), but it has since been modified to work with SDL across a wide range of various platforms, including Mac OS X, Windows, Linux, BSD and BeOS.

Aleph One supports Marathon 2 and Infinity's data files, and as of version 1.1, those of the original Marathon as well. Previous versions could only simulate the first game through a fan remake called M1A1.

Yeah, all in all, they're not exactly the friendliest community (though I have to admit I did add fuel to the fire when I insulted back). In fact (despite Marathon being originally a Mac game) Mac users would probably be better off with the Doom community when it comes to harmony.

all I got were a bunch of insult responses, telling me to buy a new computer.

Insults are counter productive and only aid putting off a person's support for a project. Its a pity they allow such behavior there. Well, on the bright side, there's little chance anyone is going to tell you to "go buy a new computer" around here Wink

It's worth noting that the current beta releases require 10.7/Lion or later. I tried asking them to see if they'd add at least 10.5 & UB support by the time of the final release but all I got were a bunch of insult responses, telling me to buy a new computer.

For those of you that are both fond of this game and the happy owner of a Wii, I've started a while a go to port Aleph-One to it : It's not really usable right now, but I hope to improve this !

For those of you responding to the first filter that also have dev skills, you may help me complete this project : I'm stuck by start-up crashes, probably due to sound engine, and would appreciate some hints !
