	0000.png (209,496 bytes) 3 hours ago Uploaded by Skeleton081983 I compiled myself a custom mame 0.289GIT version with "hap revert fix" in namcos22_v.cpp file. Now the distant scenery ground level when reaching finish is totally beige, light grey, almost white, without snow texture.

No.24397 hap Developer 2 days ago	That sucks, it means my assumption was wrong here. It should be easy to fix. Did you know of this bug before 0.288 was out, or did you find it just now? If former: although mametesters.org does not accept bugs from nightly builds, https://github.com/mamedev/mame/issues does. Then the issue would get fixed before official MAME release.
No.24398 Skeleton081983 Tester 2 days ago	I noted this bug also in some ASHURA's nightly build (sure in latest two GIT builds) before official 0.288 was released today. In official 0.287 version no red polygons are present in this situation.
No.24399 Skeleton081983 Tester 2 days ago	Other Namco system 22/Super system 22 games seems ok.
No.24400 Skeleton081983 Tester 3 hours ago	I compiled myself a custom MAME 0.289GIT version with "hap revert fix" in namcos22_v.cpp file. Now the distant scenery ground level when reaching finish is totally beige, light grey, almost white, without snow texture (see my new screenshots uploaded on 30/05/2026). I tried to compile a new custom MAME 0.289GIT with full revert namcos22_v.cpp file in this commit (https://github.com/mamedev/mame/commit/317622a33cbb5c0993b6b4296b9baaa079ae9607) and now snowy texture reappears on distant scenery ground level, like up to the official version 0.287. No issues on other Namco system22/super system22 games. Anyway, I don't know what the original behavior of the coin op was, if with a totally beige/light gray distance platform or with a snowy texture.

No.24402 hap Developer 1 hour ago	I'm fairly sure it's meant to be opaque, no texture.
