Summary 09121: shadowld, youkaidk1, youkaidk2: strange gameplay
Description Hello.
Emulation for that game is strange if comparing with the arcade.
MAME gameplay use default difficulty rank A settings so as the arcade video capture too.
I had used cheats only to recover energy and jump over top of some enemies. However not using cheats is the same gameplay behavior. That game is hardest.
Emulation has moments enemies need more hits than the arcade.
Arcade is much more easy and has less enemies in screen.
Other strange detail is the red fire demon. That red demon appear in MAME video in 12:25 if touch the player character lose all energy and not having energy recover item is game over.
If you watch the arcade video gameplay will see that red demon appear in intervals. In MAME gameplay the interval is much short and then in more others intervals that red demon appear in group of 2 or more in screen so almost impossible finish the game. In MAME gameplay in last stage even moving the player character faster to ahead that demon appear in end of stage so much hard to move in the clouds so I had used the cheat "to fly".

Please compare the videos. Arcade are 3 videos in sequence.

MAME 0.274 gameplay




Arcade video capture











In MAME if not moving the player character the more faster to ahead the red demon will appear in stage 2 and in some intervals in groups of 4 or more at same time.
You think that has anything wrong in that game.
Try play from stage 1 even with cheat "infinite energy" enabled. Red demon will appear in stage 2 and then in short intervals in groups. The gameplay will be absurd.

Have an nice day.

A quick play test tells me youkaidk2 feels easier than youkaidk1
Does youkaidk2 have the 'strange gameplay'? If no, then it's cause of the ROM revision.

Yes.
In MAME in some moments has more enemies, need more hits in few enemies and red fire demon appear in intervals more short than in arcade video capture.
