Re: Sony PVM and MiST

I think it won't work, as the DB9 is a digital RGB input, needs TTL level voltages (5V) on red, green and blue pins, but the MiST(er) provides only maximum about 1V. The FPGAs have analogue video output with many colors, while CGA standard uses only 2 values per color (0V=off, 5V=on), and a separate...

Re: Some newbie questions - Atari ST, supported joypads, keyboard etc.

... When I open the MiSTer page on Github, I see no Atari ST core. Is there currently none, or can I use the official one from the MiST? (I can live without it if there is none)... It's called FX CAST ( C ycle A ccurate Atari ST core), and can be downloaded from here: http://atari-forum.com/viewtop...

@Drog - Do you know if the HT1080z has been ported over to the Mister? someone was asking me and I dont follow the Mister stuff too closely..

Re: Genesis Core

I thought the whole point of FPGA was that mimics the hardware, in this case the Genesis, so if this is the case then why do some games have graphically glitches that the real hardware doesnt? Give me source code of ASICs used Genesis and it will mimic the hardware. Do you think it happens by twist...

Re: IO Board _ Weird colors

I think you should adjust this option from 0 to 1:

ypbpr=0 ; set to 1 for YPbPr on VGA output.

Hi! I'm absolutely no familiar with Atari ST hardware, but the floppy drive implementation should be similar to the solution used in the case of Enterprise 128.

It's very unlikely, as USB FDDs are designed for PCs and use different format (720kB) than Amiga (880kB).

What about pushing the rightmost button on the front of the MiST after mounting the disk image? In most cases it resets the given core.
