Strange problem with booting games?

Hello, everybody... I have tried many times to load some of demo games(For the C3, like the REM Alien invader game) onto a SD card and run them without any luck. When i load the game to the Propeller RAM or EEPROM, it works just fine. Also, My loader(PASos) will load any other program except for those game files. I follow the same exact procedure every time and it still doesn't boot up. Am i missing something? Other demos(Like the Graphics demo, color palette, tv terminal...) all work just fine... This is not of huge importance, but i hate not being able to figure something out:) Any ideas?

    Not an answer, but I ran into this a while back with Propdos/Femto. It would never load the Defender game.

    I'll be watching this thread... I'm curious as well.

    You really need to format your SD card with 32K clusters. The program loader used in FemtoBasic and many other programs can't handle a program broken up into several different non-consecutive clusters on the SD card. If your SD card is formatted with 16K clusters and files are created and deleted, sometimes a 32K program file will be split into two 16K clusters that are not consecutive and won't load. I think Kye's SD card driver handles this situation properly, but it's better to just format the card with 32K clusters.

    @Mike... Thanks for the help. I will have to try it and see if it works... I never would have even thought of that:)

    Try using the bootloader I made for the C3 and see if you can load up those games.

    ftp://ftp.propeller-chip.com/PropC3/Games/Jay_T_Cook/jtc_c3_bootloader_v002/

    and try these binaries

    ftp://ftp.propeller-chip.com/PropC3/Games/Jay_T_Cook/C3_sd_files/

    I know the SD functions on the C3 were a little different than a standard propeller setup, and I know the loader is not perfect either because it will not load the Defender game (which is due to the SD loader routines not clearing out all the HUB memory before or clear out the rest of HUB memory after). But Alien Invader and many others should work with this loader.

    @Mike... It says that my card is already formatted with 32 KB clusters. It also says that it uses the FAT file system. There is an option for FAT32, but i don't know if that will work?

    @JT... I appreciate the advice, but the OS that i made is supposed to work and i can't give it up now. I will have to find some way to get it to work... Thanks for the thought:)
