[N64] Turok- Dinosaur Hunter (Europe/Japan)- Copyright screen flickers upon boot #977

Open kev4cards opened 1 year ago

kev4cards commented 1 year ago

Since the improvement of SI DMA read timings in commit cb01795, Turok- Dinosaur Hunter will automatically show the controller pak management screen upon boot with an accompanying copyright screen flicker in all revisions of the Germany and European regions. This can be averted for the Germany region by launching the debugger prior to game boot and setting controller ports 2-4 to "Nothing," as, by design, this will lower the SI DMA read timing. Alternatively, pressing start will advance you past the controller pak management screen. Further timing improvements across the system should clear this problem for all controller combinations and regions. Additionally, copyright screen flicker will occur with Turok- Dinosaur Hunter (USA) and can be avoided with the aforementioned workaround. Revisions 1 and 2 do not show flicker with default settings. NOTE: Save files are not affected by this issue. However, pressing A at the controller pak management screen will delete the selected save file.

The controller pak management screens no longer exist as of commit 6bf0d1f. However, the copyright screen flicker still occurs in the USA region with that commit. That changes to the European and Japanese regions by commit 0130187. Therefore, I wish to keep this issue open until more stability is achieved.

Situation remains unchanged as of v139 release. Issue title is updated to reflect the remainder of the main issue.
