Does anyone know if the v102 Japan ROM can be used to update all v100 DDP2 carts? From what I can tell, it seems like the region is read from the ASIC on the cart, then the appropriate region is loaded from the (one) ROM.

I'm interested in using the shot type switch mechanic introduced on v102. On a side note, does the region change anything besides the region/title screens?

Trap15 confirmed that the same ROM can be used to update all DDP2 carts regardless of region. The region is read from the protection ASIC and the appropriate data is read from the ROM.

I'm still curious if there are any differences between regions other than the title/region screens.
