Goldmomo's Fun Projects
Atari assembler experiments are the main attraction here: GTIA graphics, sound tests, player-missile sprites, boot loading and hands-on 8-bit hardware work, surrounded by older FPGA, Amiga, NES, GBA, Pokemon Mini, Goldmomo Mini and WonderSwan projects.

Featured Projects
Atari is now the main project, with the other fun experiments kept close for browsing and archival value.
WonderSwan
Picture converter, text demo and HBlank interrupt demo for WonderSwan Color experiments.
WonderSwantools
Amiga
Amiga projects: SPOD, Mystic Island and classic archive material.
AmigaAGA
Game Boy Advance
Framework notes, thesis archive, graphics tests and small GBA demos.
GBAARM7TDMI
Pokemon Mini
Software sprites, line drawing and hardware sprite examples.
Pokemon Minisprites
NES
Picture conversion tooling, first-program tests, sprite demos and MMC3 HBlank experiments.
NESMMC3
Goldmomo Mini
Early FPGA game system experiment on an Altera DE1 board with custom CPU, GPU, IO and emulator.
FPGA note: this was one of my first FPGA steps. In hindsight, the code could be much simpler, cleaner and more optimal today.
FPGADE1
Goldmomo Endlos
FPGA console work, UCore, UCtrl, documentation, tools and archived daily build resources.
FPGA note: these are early learning projects. Looking back, many parts could be implemented more directly and efficiently.
