Complete reverse engineering, emulation, and preservation of all Fisher-Price Pixter device variants and nearly all cartridge games, documented by Dmitry.GR.
Key Takeaways
Pixter Color uses Sharp LH75411 ARM7 SoC with no cache, no MMU, no MPU, no cp15 – every optional feature absent, intentionally cost-reduced.
Game cart ROMs contained almost no recognizable ARM/Thumb code; most logic runs inside a custom VM with distinct instruction sets per device variant.
ROM extraction required bus-snooping the shared memory bus while suppressing the SoC boot, exploiting the fact that all memories share address/data lines.
Four distinct Pixter hardware lines (Classic, Color, Multimedia, 2.0/Plus) each got separate emulators; cross-compatibility between Classic and Color carts was preserved via a bundled adapter.
25 Classic and 32 Color games documented; Wikipedia records corrected; file formats, VM specs, and disassemblers published in appendices.
