The Saturn BIOS does not (un)initialize the DSP. Without zeroizing the DSP
program, the SCSP DSP appears to have a program that continuously writes to
0x30000 through 0x3ffff in sound RAM, which has the effect of destroying any
samples stored there.
I might later question this decision.
I liked how each "hardware" example was roughly one self-contained file. In the
"input_keyboard" case, this is no longer true.
This improves ttf-convert slightly:
- variable size glyphs
- initialize metrics for glyphs with zero-size bitmaps (e.g "space")
- move the font/serialization structures to a common header
The keyboard example includes keyboard layout data for the HSS-0129 (Japanese)
Sega Saturn keyboard.
