Bionic Commando Public Release MiST(er)
Added 2019-11-29 07:27:09 +0000 UTCI am releasing the Bionic Commando core only slightly improved over the beta. The scroll related glitches are almost gone but there is still no sound. Actually, I am precisely releasing it because there is no sound. In computer simulations of the core I do get sound. The attached file is the output of a long simulation of the MiSTer core. But for some reason it doesn't work once loaded into the FPGA.
I think at this stage it is better to open it to everyone so other developers may find it interesting to look into it. Bionic Commando uses an YM2151 (JT51 core) which is a very important chip going forward. I do not know if the issue is in JT51, or in some other piece of this complex system. CAPCOM did mix the sound system with the protection MCU and that doesn't help to debug things either.
You can get the core from the usual repository or via the update script. Source code is in the usual place too.
