What is shown

The game works very well in the modes and scenarios I tested (just some 55fps slowdowns on initial load, first 10 secs aprox) . I tried several games in the collection and various options, without encountering gameplay problems or visible graphical glitches.

Working in my tests:

• Playing Tetris Time Warp and several older Tetris titles.
• Pausing and resuming.
• Leaving one Tetris title and starting another without restarting the application.
• Vibration and visual effects.
• Video playback.
• Watched-video progress is remembered, so save functionality appears to be working.
• Music without shuttering
• Tested many languages and no problems shown.

Approximate memory readings:

• VRAM use : around 2 GB
• Tetris Time Warp: around 2,270 MB RAM.
• Older Tetris titles: around 1,000 MB RAM.

I also tested running the game from an HDD insted SSD and did not notice any performance difference once the game starts.

No problems encountered so far, although this was a selection of mini-games and options rather than an exhaustive test of the entire collection.

Current blocker

None encountered during the tested gameplay.

Tetris Forever (PPSA25646). Linux 7.2.11, Ryzen 9 7950X, RX 6650 XT, RADV Mesa 26.2.6, Release.

Setup:

• Relinked with relinker --registry --rpath <build>/core/libs/libs eboot.elf app.elf.
• Run with APS5_PLAYGO_UNLISTED_CHUNKS=installed.
• Input: Cross every 12 s from 30 s.

On main (b415263451 plus my #14298, which only adds a crash report) it reaches the "Chapter 1: The Perfect Game" museum timeline correctly, exit 0. It runs at only about 3 FPS once the timeline is up.

Why it is slow.

• CPU, not GPU: APS5_PROFILE_GPU=1 shows about 50 ms of GPU time per 10 s, the draw cache hits 100%, and there are 3 presents per second.
• Copies: perf shows about 90% of CPU time in glibc's large memcpy, called from ReadColorTarget and WriteColorTarget in Graphics::Draw. Every draw copies its linear colour target in and back out: up to 3840×2160 RGBA, about 32 MiB, each way.
• The targets: a local diagnostic print showed six linear colour targets from 3840×2160 down to 240×135. All lie in one 1.5 GiB direct-memory range that is registered and watched, but none is ever imported. The shutdown counters show color target 0/0/0.
• The refusal: the colour-target import gate in importRunAt refuses them through importStaysWatched. On this host the start-up probe reports that host-pointer imports are "compared", meaning they lose write protection, while dma-buf imports "stay watched". The gate requires a watched host-pointer import, and a shared-backed range is tried as a host-pointer import first.

A local experiment, not a PR. It changes two things for shared-backed ranges when only dma-buf imports stay watched:

• import them through dma-buf directly;
• let the gate accept them.

Same input and run length:

Build	FPS after the first minute	Colour-target imports
main	about 3	0
experiment	59.94 throughout	3 made, 0 refused or failed

The timeline screenshots match, apart from the animated background. That is one run per build; the difference is far beyond run-to-run variation.

#2434 (dma-buf before host pointer when host imports lose write tracking) covers the import-order part of this. The colour-target gate (importStaysWatched) was added to main after it.

Not verified: the classic games inside the collection, audio and other GPUs.

AI-assisted analysis: yes.

Follow-up Linux performance validation, PPSA25646 v01.007.000, RX6650XT/RADV Mesa26.2.6, Ryzen7950X, Linux7.2.11.

Pristine main 26fa1212b82f and integration 6384740a031c both reached the same 1920×1080 PLAY TETRIS! / Chapter1 The Perfect Game / explored0% chapter-selection menu. The integration refreshes #2434 onto main and adds a generic watched-DMA-buf ColorTarget creation/refusal fix.

Official 30-second traces at160–190 seconds: main 5.509FPS (166 presents/30130.067ms); integration 59.940FPS (1799 presents/30013.322ms), with no trace drops. Both completed ordinary close with exit0. Reviewed captures at150/195 show the same menu; animated background video phase differs. These are menu results, not a gameplay or audio verification. Separate fresh saves/caches were used, with no input during the window.

Exact source branch, complete official summary lines, traces, screenshots, GPU test logs, negative controls, and compatibility patch. The same4 existing tests pass on main/integration;3 import tests pass on integration,0skips/VUIDs. Full AGC scope, Intel, Windows, and further gameplay have not been validated by this run. The import-selection PR remains unmerged; these changes are not in main yet.

AI-assisted:yes.
