Minigen is a small binary file creation utility for numbered custom minipsf blocks.
Syntax: minigen [out basename] [file count] [hex string]
Minigen will produce the number of files that has been specified by file count. The file content is determined by hex string. In the string, you can embed a single special symbol NN, which will be expanded to little-endian integer.
Example of output:
C:\> minigen gametitle 4 NNNNNNNNa0380408
Created gametitle-0000.bin => 00000000a0380408
Created gametitle-0001.bin => 01000000a0380408
Created gametitle-0002.bin => 02000000a0380408
Created gametitle-0003.bin => 03000000a0380408
To convert them to minixsf, you will need a proper converter, such as rom2snsf or rom2gsf (embedded in saptapper).
C:\> for %a in (*.bin) do saptapper --rom2gsf --lib gametitle.snsflib --load 0x80b1248 --psfby laala "%a"
