that sucks, but thank you for the confirmation.I have an original PCB and I can confirm that is does NOT save 'high scores'

Likewise! @SnakeGrunger If you have more of these boards, I would like 1 or 2. Thanks.Hey @SnakeGrunger are you offering more of those reproduction option boards for sale by chance?
Stupid me recently ordered 50 wrong IC's for Naomi cart conversions, and am now all worried about getting the wrong things...Here are the eproms I used :
CHR0-3 : 27C080 (1,024kb)
SHA0 : 27C040 (512kb)
SPR0 : 27C1024 (128kb)
VOI : 27C160 (2,048kb)
MPRL : 27C240 (512kb)
MPRU : 27C240 (512kb)
Thanks! And good call. I'll just do that.@rewrite yeah those are correct (just double checked with my personal copy). 27C240 are not common but I just take off the stickers from the ones already on the NB-1 board and rewrite new data.
Thanks!!I have the files. I’ll send you a PM.
They are equivalent to 27C4096 which are very easy to find.@rewrite yeah those are correct (just double checked with my personal copy). 27C240 are not common but I just take off the stickers from the ones already on the NB-1 board and rewrite new data.
Thank you very muchFiles sent.
is the conversion possible with that game?Just bought a SWS 97 donor I'm hoping to convert, any chance you still have one of your reproduction boards available @SnakeGrunger ?
I hate this method alone. The power supply rails need to be regulated at 3.3V yes, but the address lines also need to be capped at 3.3V otherwise it will cause damage to chips in the circuit, see this blog post : https://db-electronics.ca/2017/07/05/the-dangers-of-3-3v-flash-in-retro-consoles/is the conversion possible with that game?Just bought a SWS 97 donor I'm hoping to convert, any chance you still have one of your reproduction boards available @SnakeGrunger ?
the roms and the object board have to be flased with ne files? and a 3,3 v pover converter mod be done?
thanks
