OCM-PLD Pack 2.3

Topic: MSX Revival
Languages:

A new version of KdL's 1chipMSX firmware has been released, a practical - if not essential - update for 1chipMSX'es. New in this version:

  • Fixed a bug inside of "vm2413.vhd" source code
  • Modified DIP-SW4 original function with 2MB/4MB memory mapper selection
  • There is a separated PLD file for every keyboard layout; these files have been optimized with Quartus II 9.1sp2 Wed Edition
  • Updated DIP-SW User Manual [esemsx3\src\doc\dipsw_v23.htm]
  • This package will have the full source code from now

A tip: to bypass the error messages of MSXDOS2 when drive B: of the MegaSD is empty, make an ASSIGN B:=A: at the prompt of the command line.

Hi all! Smile

A note to obtain a correct PLD file from a clean and uncompiled project of Quartus II 9.1sp2 Web Edition:

1. run [c:\altera\esemsx3\emsx_top.qpf] to load project
2. start compilation for a 1st pass (wait for done)
3. start compilation for a 2nd pass (wait for done)
4. go to create emsx_top.pof and emsx_top.pld files

I don't know why but the PLD obtained from 1st pass isn't equal to that of next passes.
Probably it will not be optimized. Question

I confirm!
To optimize design (and PLD) you can use Quartus II Design Space Explorer.

These are the best results for v2.3uk:

Simple test of audio noise:

VGA cable noise is very low with my LCD display and very high with CRT display.
A conclusion is that an external filter is necessary to remove it because 1chipMSX have none.
I advise to use a LCD display.
