There is an alternative way to go, which is to use the hard disk of the host machine as a pseudo-CD, by reloading datafiles at runtime. CodeWarrior's ComUtil already does this (I think), and Craig Graham has been posting about a ARS utility to provide the same functionality with GNU. Hence you can reload into RAM whenever you want. Lewis Is it at all possible to boot from the Yaroze CD, swap in my own CD, download my game to the Yaroze from my computer, and have my game read from the CD? I had thought this would be possible (why else include the CD reading commands in the libraries), you just couldn't create a bootable CD, but I haven't had any luck at it. Any disks I've created (1 track, CD-XA Mode 2), don't return a directory when DIR is done from SIOCONS. I would like to be able to write a game using all high-resolution, high color graphics, but there just plain isn't room in the Psx's memory for what I want to do. One screen of 16-bit, 640 X 480 graphics takes up about 600K (my current titlescreen does, anyways). While there is plenty of room for a little area of tiled graphics, I want to write an RPG with large, detailed artwork, with different graphics sets for different areas, and maybe the occasional full screen picture (or maybe just some real good storyline animations? I dunno...). -- - Dreamwriter Dragon dreamer@sinclair.net -==UDIC==-
