Speaking of pal games, European language versions of Secret of Mana might need a Gamma fix to. Only ID that enables hires is 1016 again, which causes high Gamma in menu. All other Preset IDs that I testet even the official ones according to the DarkAkuma sheet give a C7 error. Though I only testet the German language version.
Tommorow I also will play through Rendering Ranger again with the latest Overscan Patch and give a report.
Like I said here, I played through Rendering Ranger R2 again, now using the latest all in one patch.
Game was playable from start to finish. No sound problems. No graphic issues in stage 7.
But: See this Explosion issue therourke posted for Gun hazard.https://youtu.be/ijvyIbQXGys
This happens here also quite often with explosions or even enemies or bosses, when there is a lot of stuff going on. Also flickering sprites or HUD can happen with lots of stuff going on.
When the big door opens at the boss fight in stage 5, the HUD had graphic issues. (part of the helmet was missing)
I don't know if These are bugs or the game is just that demanding.
EDIT: I played on hard, Preset ID 0000 and with cheats, just to specify that.
For the mana test: 10AF, 10B0, 10B1, 10B2, 10B3 (different mana IDs)and 10F6 (Romancing SaGa 3) all gave C7 error.
