Hi La vache,
thanks for testing and reporting back about the problem. But it's not a bug, it's a feature to keep the difficulty level low
(just kidding).
You can either fix it with SH3 Commander as you did (but one must be careful to set the RndGroup number correctly) or just remove the 'Class' line for the entries. I guess I will do this and upload a new version with generic type=4 entries
Best, LGN1
