zzo38computer has updated his Xy-Mini emulator.

Changes:

I posted the fixed version now. Now it works correctly.

Xyds: http://zzo38computer.cjb.net/nitro2/Xyds/
XYMTOOL: http://zzo38computer.cjb.net/xym/xymtool.zip

To use XYMTOOL to patch a .nds or .ds.gba or .sc.nds file:
xymtool -f xymfilename -p xyds dsfilename

XYMTOOL includes source-code. It also includes TILEMAKR and MAPMAKER, which are used to create tile sets and maps for XY-MINI (monochrome tile mode only). 8ted can also be used to create tile sets for XY-MINI (but TILEMAKR has a few features that 8ted doesn’t have). If you want to use XYMTOOL on a operating system that isn’t Windows, you have to compile it using FreeBASIC.
