OutRun - Road glitches after stage 3 #132

Out Run (Japan)-191116-163107

After stage 3 in OutRun the road completely glitches out. The car and roadside object sprites still show properly but the road stays like this for the most part until the end of the game. This bug is apparent on both this core and the SuperGrafx core.

The core version is v0.9.38.7.

confirmed as of commit https://github.com/libretro/beetle-pce-fast-libretro/commit/5a2803fab22f73513df2c76aa6e2a4a88ba3ee3d happens on some specific branch i think (left-right-right for example)

well, it must be a game issue thing, since even mednafen pce has the issue. might be better checking if its already reported upsteam, if not best to be reported if its not a game issue

i cannot get a specific pattern to replicate the problem. sometimes it comes out, sometimes not. usually it starts happening on the last part of stage 3 before the checkpoint for stage 4

in any case, its an upstream problem

Need accurate core for this to never happen. Also need accurate core update to 1.29 upstream
