Will the problem with external video cards like Playsoniq be solved soon? Sad Remember that in versions <=2.3 this hardware worked like a charm...

Hi spl, my Franky cartridge seem to work very fine with OCM-PLD v3.2.3
I think because the "VDP TH9958 INT_n" issue was fixed (2014.07.27)

Hi Smile I'm going just to test it with my Zemmix Neo. If it's OK, I'll update also my 1chipMSX Smile

Thanks! Big smile

@st1mpy: The connection pinout between the PBC and the DE1 is the same as using the DE0, I think you can use the PBC on your DE0 wdthout any modification,I hope,
If is there any DE0 user near Barcelona, pleasse contat width us to test PBC works width DE0

Thanks.

x-nen, yep, it is the same layout, but the DE0 lacks audio output that needs to be implemented in the expansion board, as you can see in caro's schemas... perhaps the audio output can be implemented in your expansion board with the help of the debug pins?

I'm from Madrid, maybe can I test the board for you?

3.3RC3:
- fixed the MainRAM clear function and rewrited the MegaRAM clear function
- new IPLROM with a BIOS by 304kB (+16kB free on ECPS, -1sec on loading the internal BIOS)
- new batch files that simplify the compilation of the two supported machines (ocm and zemmix neo)

In my latest OCM-BIOS had been removed the Drive B: from the system, a temporarily fix for the issue of CTRL-key.

Unfortunately this setup of MegaSD do not permit to mount the disk image with EP.COM that it was possible in the original configuration of 1chipMSX (by default on Drive B: only).

Following procedure can enable you to one or more mounting letters:

a) run ESET.COM (http://www.big.or.jp/~saibara/msx/ese/)
b) press [ E ] for the option "easy setup"
c) press [ C ] for the option "connect drive"
d) press [ N ] and [ 2 ] if you go with Drive A: + Drive B:
e) press [ RETURN ] on B: line and make it to "ID1 -- Error" using the arrow keys
f) exit from setup and make a soft reset (a "reset" command is present with COMMAND.COM V2.44)
g) at prompt you can mount the disk image with EP FILENAME.DSK B:

Anyway I think to do to fix the CTRL-key

Cheers.

@KdL

Back in 2008, HRA implemented the turbo-blitter option (500% faster), activated/deactivated by pressing SHIFT+F12. I thought that this feature was present in your firmware too. Could you please implement this feature too?

@KdL

I just read the v3.3RC3 firmware source code, and noticed that the turbo blitter seems to be there, but it isn't assigned to any key combination. I would like to ask you to assign it to SHIFT+F12 so it can be easily enabled/disabled on the fly then.

If possible, I would like to suggest a feature: add an option to select if the 15KHz RGB mode will output "CSYNC + audio" or "HSYNC + VSYNC". The separate sync would allow the existing VGA->SCART adapters to be used.
