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.
