First of all, this game has in-game rom check. The following codes cause game crash unless you set "skip rom error".

And some codes are updated.

"player speed" : rewrite routine. adjust item values.
"max bullets up" : add new as "test" code. Yellow weapon seems not to get "max bullets up".
"sound test mode" : rewrite routine.

Normal shot level 1 is easy to understand for "max bullets up".

Posted: **Wed Feb 07, 2024 10:03 am**

First of all, this game has in-game ROM check and any ROM codes except "sound test mode" cause freeze/crash the game.
Someone reported as "bug" to MAME testers in the past (See https://mametesters.org/view.php?id=4119).
Please don't report because it is due to cheat, not MAME bug.

You note that "invincibility" in the database based on 0.259 coflicts with "skip rom error" by my post about in-game ROM check.
If you set both codes together then turn off either of one of code, in-game ROM check revives again.
