Extract the audited adapters and card transport onto master without the held selector/menu stack. Keep adapters and codecs tied to mod activation, use overlay ABI 33, retain rejected-load protection on codec registration, and refuse extended-card codecs in netplay before frame zero. Preserve default atomic save publication and guest-visible write failures.
Many PS1 renderers drop a primitive whose depth index falls past the end
of their ordering table. Raising that limit can write past the table, so
a title can now list such guards in game.toml with the register that
carries the index and the last safe value. While a trusted mod has called
psx_mod_set_draw_distance_clamp(1), generated main-EXE code clamps that
register before the guard runs, so far geometry is kept in the farthest
slot instead of popping in later.
- Off by default and reset at every session start, so netplay and every
title that lists no sites run unchanged; with no sites the generated
code and declarations are byte-identical.
- Main executable only: the full instruction word is the guard,
generation fails on a mismatch or a load-delay hazard, captured
overlay code keeps its own code (the sites are not part of the overlay
config identity), and the dirty-RAM interpreter applies the clamp
where the game's text image holds the listed word.
- Compatibility: code_generator.cpp is a codegen-hash input, so the
codegen hash and the overlay-cache tag change for every title, sites
or not. Savestates from earlier builds are refused, and overlay shards
rebuild once on first visit. Generated code and behaviour are
unchanged for a title without sites or with the switch off.
- Tests: draw_distance_codegen_test (config rules, emission, guards,
declarations, overlay identity) and draw_distance_interp_test (store,
switch, interpreted guards); the session-reset guard covers the switch.
