Re: Maybe some new technical information about the Yamaha YM2612

Outside of telling how the phase modulation works and the tables there isn't anything new there. I does mention test registers explicitly though, but no extra info haha. Values in the tables aren't very useful for MD though, because the YM runs at 8MHz there, so all the values are slightly too big. ...

Re: How does work SRAM on everdrive?

Some RPGs have 32KByte save memory. Emulators don't tend to emulate more than 64KBytes, regardless of what header says when I tested it long ago.

Re: How does work SRAM on everdrive?

You may also need the backup RAM header bit too just after the RAM range. "RA"+two bytes that tell what the memory is and how it is connected.

Re: Cartridge copy protection

Trying to talk to the flash chips is one way to go about it, if the chip isn't giving expected response you knew you're not on original hardware. Most flash chips have means to ask an ID from them. You could even put saves on the chip too if the sectors are small enough, beware of limited write capa...

Re: SHMUP scrolling game

You only update the row and column just beyond edge of screen towards scrolling direction, no need to deal with entire tilemap. Almost all games work that way too.
