Summary	08517: slapfigh: Weapon select occurs automatically (as if button stuck down)
Description	Flying over a power up star the selected weapon is automatically selected without user interaction i.e. as if button 2 was stuck down. Just noticed in 0.247, but does not happen in (much) older builds (e.g. Mame2010 - which I think is 0.78). Sorry I do not have access to all builds to say exactly where the bug started.
Steps To Reproduce	Start game. Kill enemy to release power up star. Fly over power up star SPEED (first highlighted powerup) will select automatically instead of by pressing button 2. Bug continues with all future powerup star collection. This issue is NOT present on older builds (range of working builds unknown) using same hardware so I think I have eliminated possibility of an actual stuck button.

There doesn't appear to be an issue with emulation. Check your configuration/controller mapping to make sure there are no conflicts. A fresh install in a separate folder can't hurt to help identify the issue as well.

No.20851 Augusto Tester Nov 22, 2022, 05:48	Not any issues in current version. Fujix and Tafoid are much blessed for having an job in project =)
No.20863 Fuzzweed Tester Nov 25, 2022, 23:05	Ok, there IS something going on here. Just tried tiger-heli in mame247 and it's releasing all it's bombs straight off ie 2nd button stuck effect. I'm not getting this in older mame builds, and I'm not getting this in newer ROMs in 247. What can I give you that will help determine the cause?

No.20865 Osso Moderator Nov 26, 2022, 06:56	MAME is at 0.249 right now, could you see if it still happens with that?
No.20884 Robbbert Senior Tester Dec 1, 2022, 12:07	I'm utterly hopeless at these games (slapfigh and tigerh), but I can't see anything wrong with them. Unable to confirm this report.
