[goldnaxe1] game locks in stage 2 #5

Closed jotego closed 2 years ago

If the enemy is pushed off the cliff, the game doesn't let you advance. The go sign never shows up. Slashing the enemy lets you advance. Either killing method is ok in MAME.

Music gets corrupted too.

It locks even with git co 8072eb3 -- jtframe_68kdtack.v on JTFRAME
It also locks in ac1f52e
