RQ: Disable solid alpha-blended tiles for Sexy Parodius (konamigx.cpp)

Mon Feb 18, 2019 12:01 am

There is a blue wave effect on stage 3A of Sexy Parodius that adversely impacts gameplay by concealing sprites. I think it would be better to not display it at all, which is how it was handled in MAME before v0.168
Video to demonstrate what I'm referring to: https://youtube.com/watch?v=9cloty1wa1w&t=17m52s

The question is whether this happened on the real hardware as well (so it's a bug in the game and not in mame, and it needs to stay this way as it accurately emulates the real thing), or whether this only happens in mame and not on the real hardware (which makes it a bug in mame and it needs to be looked at).

Whichever it turns out to be, you may want to sign up for an account on mametesters [1] and report a bug for it.

Actually, reporting bugs on known issues (konamigx.cpp driver has inperfect graphics and sound flags) is not permitted. Please be mindful of pushing people to mametesters.org that they need to respect the reporting rules: https://mametesters.org/rules.html

As far as konami driver work goes, there is a branch on Git which may have it fixed, I don't know. There hasn't been much work done on the source by the people involved for a long while as other more important/pressing items have taken their time.

Ah. I didn't realize the emulation for this one was known to be imperfect; I didn't check and just assUmed that the emulation was ok before. My apologies.

PS:
I seem to vaguely remember that reporting bugs on known imperfect things (like graphics) was still allowed if there was a (serious) regression, which seems to be the case here, but I could be wrong on the matter.
