Fast RNG algorithm

Just found a nice pseudo random number generator algorithm suitable for S1C88. It uses only 16 bit numbers and is very fast when implemented in assembly: uint16_t xs = 1; // initialised with a non-zero seed xs ^= xs << 7 xs ^= xs >> 9 xs ^= xs << 8 Here is implementation for several processors inclu...

Re: Multi ROM for DITTO mini PUBLIC BETA!

Bs it normal that the boot up seams to be very energy consuming, as the low battery animation is showing on every start and boot of every game?

Re: In-Progress Pichu Bros. patch (feedback requested)

Re: In-Progress Pichu Bros. patch (feedback requested)

I suggest that you change the game code from MBRJ to MBRE. Also write the game name in English in the other 12 chars that follow. That would be consistent with the other translations. I am doing a patch for the DITTO mini bootloader that recognizes game based on the game code, hence my concern to kn...

Re: Multi ROM for DITTO mini PUBLIC BETA!

Fixed the freeze too. The new code is re-uploaded in the initial post. Also the new sources. Currently fixes are needed for race, breeder, togepi, pichu and tetris. Both version of tetris work with a trick but the other 4 games need a patch. The patch is applied on the first start of the bootloader....
