Note on Total Ships column

The value for Total Ships is taken from service menu “function” (aka setting) number 7.

Accessing service menu

For MAME press F2 from attract mode, hold F1 and press F2 until you reach the settings page, press F1 (without F2) to cycle through to function 7.

For JROK press what is presently the 2P start button on the front right hand side of the Arcade1up cabinet (equivalent of F2 in MAME). The equivalent of F1 in MAME is the unlabeled button immediately to the left.

DIP Switch Settings

Wanted to check that the same ROMs were in use on MAME vs JROK and the same settings were in use. TL;DR: red ROM used in both, difficulty settings the same.

On the JROK, free play is the default, which indicated other settings might not be factory default, e.g. difficulty.

The below settings refer to the red ROM, which is named Defender as opposed to Defender WR (white ROM) or Defender GRN (green ROM) in the JROK menu.

Setting #	Platform	Value	Setting Name	Description
19	JROK	15	GAME ADJUST 2	Progressive Wave Difficulty Limit, 5-30, e.g. 5=LIB; 15=MOD; 25=CONS (Factory default=15)
19	MAME	15	GAME ADJUST 2	Progressive Wave Difficulty Limit, 5-30, e.g. 5=LIB; 15=MOD; 25=CONS (Factory default=15)
18	JROK	5	GAME ADJUST 1	Starting Difficulty: 0=LIB; 5=MOD; 10=CONS (Factory default=5)
18	MAME	5	GAME ADJUST 1	Starting Difficulty: 0=LIB; 5=MOD; 10=CONS (Factory default=5)
