This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

6502Em: Troubleshooting ======================= The Emulator runs too slowly ---------------------------- The emulator can be speeded up by turning off the 'Sound' option. On slow machines is is also worth setting the speed to 10000%. Turning on the 'Faster Hardware Scrolling' option _may_ also speed up some games. Game will run from Tapefile but not from Virtual DFS ---------------------------------------------------- Although VDFS does not need memory from &E00 TO &1900 some games corrupt the extended vector workspace in &D page which is necessary for Sideways ROMs to work. The 'Disable Tape' option can sometimes cure this. Screen is corrupted ------------------- You can press f10 to refresh the screen. Screen flickers and colours change rapidly ------------------------------------------ Some games change the palette half-way down the screen which is not supported by the emulator. A partial solution is to turn off the palette from the options menu. You can then press f10 inside the emulator until you get a desirable set of colours. I can't change drive -------------------- You should use, eg, '*Mount 0' to change drive, or you can use a command like '*DIR ADFS::0.$.Games' to change drive and directory. I can't save the screen as a sprite ----------------------------------- This option is disabled by default. To re-enable it uncomment the line '|Set 6502Em$SaveScreen Yes' in the !Run file. If the save option is still greyed out it is because the emulator has not yet been into a graphics mode - MODE 7 screens cannot be saved out. Games run too fast or too slow in Electron Mode ----------------------------------------------- The speed control works slightly differently in Electron mode - it's worth experimenting with it both UP and DOWN. Printout Appears all on one line -------------------------------- Printer ignore character is set to 10. Solution: type *FX6,0 inside emulator.
