Wheel of Fortune (USA) Intro FMV Freeze #76

Open arobotbitme opened 3 years ago

arobotbitme commented 3 years ago

The opening FMV for Wheel of Fortune (USA) freezes about midway through. It eventually does continue after freezing for maybe 30-40 seconds. Verified that this does not happen on real hardware (Model 2 Genesis w/ Model 2 Sega CD (USA) & Model 2 Genesis w/ Everdrive PRO with the same Redump bin/cue). The game seems otherwise functional; I was able to play a few full games under various conditions without other problems as long as I pressed start before the intro FMV freeze occurs.

Core info: Glitch occurs across the newest release and a few old ones I tried, but does not occur in the initial core release. Glitched: 20200620, 20210124, and 20210130 No glitch: 20191205

BIOS info: Tested using: Unofficial region-free SEGACD BIOS in root based on US Model 2 (boot.rom). Official US Model 2 2.00 BIOS ([BIOS] Sega CD 2 (USA) (v2.00).md) in Wheel of Fortune's game folder (cd_bios.rom) Official US Model 1 1.10 BIOS ([BIOS] Sega CD (USA) (v1.10).md) in Wheel of Fortune's game folder (cd_bios.rom)

Glitch occurs across all three setups.

MiSTer info: Using MiSTer framework 210109, Standard I/O (Misteraddons), 128MB SDRAM (Misteraddons), SanDisk 400gig card.

Game info: Verified image checksum against redump.org here: http://redump.org/disc/8273/ . Game is in bin/cue format.

Issue is still present in the latest build, but the duration of the freeze is now only a second or two whereas it was 30-40 seconds in build 20210130.

This issue is now reoccurring, there has been a regression most likely.
