SID Player for BBC B, Master 128 or ELK with BeebSID

A build system to create SSDs containing SID files

This includes:

sidreloc a hacked version of Linus Akesson's which is used to relocate the SIDS to page 1A and move any zero page variable down into the "language" area.

ripsid which takes the SID binary out of the PSID wrapper and generates some metadata variables and adds in a jump table that replaces ST* SID instructions with a JSR that sets both the original SID register and a copy that is used in the player screens for the display.

menu file The files are bundled up with a simple metadata files used to generate a menu file containing the song's BBC filename and the title from the SID.

players Assembler play routines and menu systems. If the main player routine (which is Mode 7 based) is run on an Electron it chains on to the SIDPELK player which starts in Mode 6 for the menu then does some garish scrolly graphics in mode 5 to keep you amused while the song plays.

Escape to return to the menu, < and > can be used to select sub songs where the are a available a song indicator will show in blue near the bottom of the screen with i.e. "< 2 >" where there are more than 2 tune or just "1" where there is just one!

The build system should work on any *nixy system. (I use Cygwin - let me know if there are any problems on other platforms)

Preequisites:

• cc65 (for the assembler)
• dfs-0.4 (see my github)
