so, does anyone have implemented any emulation of this chart?
how can I emulate a MegaFlashROM SCC+ on blue/open msx?

Bluemsx has a megaflashrom scc cart in the insert special cartridge menu.

I never used that one before though so I don't know if it is really scc+ or normal scc.

We can try to emulate it if we can get the full technical specs...

Does it worth the effort when you can emulate the roms directly with the emulator? Question And you also have the SCC-I if you want...

it is to develop roms that can be loaded in that flash
SCC-I is only emulated in the original ram charts
No way to emulate that new HW for the poor developers

Besides that. The cartridge has its own psg emulation. By emulating the SCC+ flash it is easy to develop software for it (think 1 psg for sfx and 1 psg for music).

What do you need?

The full specs and how to control them. Preferably also which chips are used, so we can look up the datasheets.

To emulate an MSX hardware you need to know:
- which chips are used (you need to emulate the behaviour and functionality of the chip)
- how they are connected to the MSX (this is how the chip is controlled from software)

In this case PSG and SCC+ are in an FPGA, but if they behave the same as the original chips, we can just say that the cart contains these 2. But there's lots more stuff in it and all of that needs to be emulated to make the software for this hardware work on the emulator in the same way, of course.

why not emulate just these two chips?
