Texturing (validated live -- game-live-textured.png, the ravine's brown dirt terrain): the wire model is Division's intensity+ramp scheme. action 26 uploads 8-bit intensity texels ([node][nbytes][w][h] + rows; type 13 = texture); texmap (12) references the texture; material (11) references its texmap and a ramp (14: lo/hi RGB); texel color = lerp(lo, hi, i/255). The backend bakes RGBA per material, uploads to GL, maps with wire UVs (stride-5: floats 3-4; stride-8/9: floats 6-7). Serial (directserial fork options, tracked in vpx-device/serialport/): - rxpollus:<us> -- receive poll tick (stock 1ms); 100us discovers inbound bytes ~10x sooner. Validated: sim advanced, camera moved with real RIO. - rxburst:<n> -- stock DOSBox re-serializes received bytes at emulated wire speed (~1ms/byte at 9600) though they already paid wire time on the real cable; a 15-byte analog reply gained ~14ms, blowing the RIO's few-ms ACK window and dropping the game into its 15-second retry fallback (L4CTRL.CPP limit=15.0 //0.2). rxburst:16 delivers buffered bytes 16x faster. game_rio.conf: realport:COM1 rxpollus:100 rxburst:16. Crash-on-advance fixed: *_TSHD.BGF terrain shadows live only in arena subdirs the search path misses; null shadow renderable was dereferenced once the sim moved. All 11 copied into VIDEO/GEO in the working image; game now runs sustained (560+ frames, textured, no crash). Details in RIO-NOTES.md. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

# The RIO drops comms if an ACK is late by more than a few ms. Empirically

|
# (2026-07-03) a SLOWER CPU makes it fail SOONER -> the ACK latency is
|
|
# dominated by how fast the game processes the RIO packet and replies, so we
|
|
# run the CPU as fast as possible:
