You can either burn a new CD and write the contents from that CD into the Simms. Take into account that the writing process via the BIOS is still the same, a bit faster, but not much. So for each game it will take 45 minutes and there are 8...... so 6 hours in total. Good news is that you only do it once and call it a day.
I have been working already a lot of hours on getting the new BIOS done. Right now, you can write individual files to the simm using the BIOS section called FILES & DISK.
Doing it, using the normal usual way where you write a new game from the BIOS or just insert a new CD, doesnt work 100% yet. All previous bugs like joystick moving too fast in the game selection menu, etc. are all fixed as well.
The other option that I'm evaluating is to sell also the small CPS3 New simm <-> TL86 adapter that I use for my tests, available for the people. With this adapter, it takes 1.5 minutes to write one simm, so in total you can have all 6 simms written in 9 minutes (as oppossed to 6 hours). I'm thinking of offering the first batch ONLY with this tiny programmer PCB + new set of 6 simms until the BIOS is 100% ready. Price should be around 500 USD for everything. When I feel that the new BIOS is 100% then I will offer the option to buy without adapter. That will make it only 50 USD cheaper, not more. What do you guys think?
You need a new BIOS. The existing one doesnt even recognize the new simms. A lot of work has been done to make the BIOS support new flashes from 2020.
