The GFX9k Lib must be assembled with sjasm. However it can be used with another assembler or C compiler by means of an export file.

With this GFX9k Lib comes a new graphics format: G9B (read specs).

The g9klib package contains 2 MSX tools and 1 PC tool. You can use V9BMP and G9Bview for the MSX and BMP2G9B for the PC (MS-WINDOWS). G9B files can be created with V9BMP and BMP2G9B. V9MP doesn't support compression. BMP2G9B can also be used to compress non-compressed G9B files.
