Ah, I got confused with this merge, I thought Retro Sonic and RSXB were still too separate games. So I haven't kept up with the news, are levels from Retro Sonic going to be RSXG, in that case?
This is kind of off-topic, but you don't have a Non-Self Booting copy of Retro Sonic for the Dreamcast laying around do you? I can only find the SB ones and I well wanted to make a SBI (Self Boot Inducer) out of the Non-Self Booting one.
