Xasm
v2.05
Archive Contents:
BasDir : A small module which provides a system variable called Basic$Dir
which works analogous to Obey$Dir. I have used it for the
examples.
Xasm : The actual Xasm patch.
XasmDoc : Hum, guess... ;)
6502 : Some 6502 examples by Alain Brobecker.
Test : A zip archive with one more test program, which assembles all
instructions in all possible addressing modes.
Chip8 : A small example game for the Chip8 part of the Xasm. It has only
one level yet. (Sorry Alain.. ;)
GameBoy : A small gameboy demo which simply scrolls a picture around, using
our gblib. The icebird has been painted by Gizmo.
Using the patch
---------------
Using the patch is quite straightforward and it should run on any RiscOS from 2
to 3.7.
After running it, you may select the processor for which you want to assemble
using the "opt" command by adding one of the following values:
+0 : ARM
+256 : Chip8
+512 : GameBoy
+768 : 6502
Then use the BBC Basic inline assembler as normal...
