GT2Recomp 0.2.0 - Arcade & Simulation discs

The GT2 Combined Disc is no longer required. Drop in your own dumps of the Arcade disc, the Simulation disc, or both — any file names — and Setup builds each one into its own native PC program. Switch discs from the settings window or, while playing, from F1 → Disc (it's the first thing in the menu). Your settings, controller mapping, enabled mods and memory cards are shared across discs, so Arcade's "Load Guest Garage" sees your Simulation garage exactly like on the console. A Combined Disc image still builds as an optional third disc if you have one.

Install / upgrade

1. Put your .bin disc image(s) in a folder.
2. Download GT2Recomp-setup.zip below and unzip it anywhere.
3. Double-click Setup GT2.cmd. If your discs aren't beside it, it asks you to pick their folder, lists the discs it found, and asks before starting — then 30–60 minutes per disc, then DONE.

Upgrading from 0.1.x: same steps in your existing folder. Your tuned settings and what you had ticked come along (the enhancement folder is renamed patches\ → mods\ automatically).

What's new

• Two discs, one install. Per-disc builds under titles\, a Disc row in the launcher, a two-row Disc section at the top of the F1 menu.
• One configuration follows you — video, audio, controller, keybinds, the enabled-mods list and memory cards are install-wide, not per disc.
• Every mod verified on both plain discs against Silent's hash-specific patch database: 60 FPS, widescreen, draw distance, full-detail AI cars and 8 MB polygon buffers are byte-identical across the Arcade and Simulation discs.
• Presets on the Mods page: Enhanced (widescreen, geometry correction, longer draw distance, full-detail AI, CPU overclock at 200% — the setup that runs best, at the original 30 fps) and Authentic 1999 (everything off). Every mod stays individually switchable.
• CPU overclock stands on its own — it's part of a good 30 fps setup with the heavier mods on, not just a 60 FPS accessory. Choosing 60 FPS raises it to 325 automatically.
• Setup runs from anywhere and tells you what it's doing — a folder picker if the discs aren't beside it, a confirmation before the long step, one live line per disc with a percentage and time estimate.
• Memory cards are backed up before every session (saves\backups, ten deep).
• Updating keeps your tuned config and merges in the keys a release adds.
• Diagnose GT2.cmd — if something won't start, run it and attach gt2_diag.txt to an issue.

Known issues

• 60 FPS is experimental and not right yet. It runs sluggish and uneven on current builds even with the overclock it switches on. Stay on Original (30 fps) with the Enhanced preset — that's a solid 30. If you try 60, give it several sessions to warm up the native-code cache before judging it, and lower supersampling first if it's still heavy.
• Mods and cheats are per disc, and each disc needs its own testing. The Arcade and Simulation discs are different programs; anything that works on one has to be verified on the other before it's offered there. Mods: done for both. Cheats: none yet for the plain discs — the published Arcade unlock codes are for the v1.0 pressing and corrupt the v1.1 disc this port runs (they broke controller input in testing), so they were pulled rather than shipped as a guess. The Cheats page says so. The Combined Disc keeps its own. Expect more mods and cheats in later releases as each is verified per disc — if you have a code that works on v1.1, open an issue.
• The first sessions after a build run slower while the game converts itself to native code; the boot "Loading Save Data" screen takes a while.
• 30 fps replays and Rally ghosts don't play back correctly at 60 FPS.
