概 要2人プレーをはじめると固まる。
詳 細When you play a two player game, when the 2nd player has died for the first time and the 1st player takes over again, there is screen corruption. When the 1st player dies again, there is some sort of crazy screen corruption which happens and the game essentially is unplayable until reset/restarted.
再現手順- Start either machine
- credit 2 times, start 2 player game
- Start player 1 and die
- Start player 2 and die
- observe graphical corruption
- player 1 dies, the game becomes unusable
追加情報First reported here:

Regression traced initially to the great galaxian rewrite which happened on 0.124u1.
At that time, game would end after 3 total deaths in a 2 player game(watchdog?).

Then, as mentioned in bug02817, with 0.128u4 the games were constantly rebooting. Quite possibly, this is due to major CPU memory addressing changes, but unconfirmed.

This was fixed in 0.128u6, game plays seemingly normal as a 1 player game, but the issue shows up in a 2 player game as reported.
