You could boot a gray PlayStation with MOD chip from the original boot discs (access card required), download your executable using siocons. While the program is running, you can change the discs. The gray PlayStation can then read from CD-R (of suitable format) and your executable may load any data files using CdReadFile(). > Alternatively, if you have Codewarrior, you can use the MWDebugIO.lib functions to > load in graphics and whatever from the PC/Mac at run-time, as and when required. > That way, Net Yaroze members could produce and distribute much larger games.

First of all, not all members are working with CodeWarrior. They would not be able to run your program. And since the transfer is done using serial communication, the transfer rate is limited to 115200 bps which is about 14 kB/s. This can be terribly slow if your program uses large data files. Loading from disc is way faster: AFAIK, the drive does more than 200 kB/s. Regards, -- Daniel Hartmeier PGP 6A3A7409 ICQ# 12742482 "The woods are lovely, dark and deep.
