OCM-PLD Pack 3.0

A new version of KdL's OCM-PLD pack was released yesterday. With these OCM-PLD updates you can inject your 1chipMSX with new features. When the 1chipMSX first hit the news, many years ago, it was just an MSX1 machine. This resulted in mixed feelings among MSX fans, who were hoping for a spectacular MSX3, or at least a turbo-R. At the very beginning it was made clear, back then by Bazix, that this 1chipMSX would only be the beginning of a long development trajectory. Throughout the years, people have been using their 1chipMSX as an MSX2 and right now an MSX2+ implementation bangs the door.

New in this version:

MSX2+ edition based on OCM-PLD Pack v2.4
Updated Switched I/O ports (-F) module to Revision 002.
New documentation and DIP-SW User Manual in the [esemsx3\docs\] folder
IPLROM module that include the Pletter routine by caro
Stable release of VDP, PSG and KANJI modules by HRA!
Improved hard reset key: one click for a fast reset
hold few seconds or double click for a complete reset
Improved code readability of sources replacing tabs with spaces
Minor fixes to improved LEs resources
Updated the [msxtools\] folder
New custom Hex files compressed by Pletter: yen or backslash, 80 columns, key click off and logo antialiasing fix
PLDs in this package: JP layout, UK yen, UK backslash and FR backslash
This release has been optimized with Quartus II 11.0 Web Edition

Anyone who dares to predict how far KdL could stretch this 1chipMSX of ours? turbo-R? Graphics9000? MSX3?

I installed it this morning and I found two important bugs:

-Cartridges are not detected on first boot, I had to reset to run them.
-Pause button pauses the emulation, but pressing it again doesn't resume the emulation.

Very nice indeed, but is there enough room for MSX turbo R, MoonSound and GFX9000 support in the OCM? I thought it reached the full capacity already. And how will MSX3 look like? Zilog Z380 and USB support? Keep up the great work KDL!

Just updated it!!
I love having another MSX2+ !

Cartridge works ok (well i tried only 1 cartrdige so far, but it works). Sonyc doesn't work at all, as somebody said, it ask for a disk (I need to try to run it from a dsk). Some MSX2+ games work perfectly, for example Gradius Legends. Also QUINPL (it's MSX2 but has 2+ screens).

But MKID demo doesn't work fine, it does big screen flickering. That's all for now, need to try more

@KdL: What you preffer, but i think following the ISO-3166-1 namig convention is a good idea, so 'Es' would be nice, but it's a little detail without importance

Sonyc works... but it's a PAL game only!
Use these steps with vga output:

a) ep.com sonyc.dsk /r /b
b) start the game
c) on black screen (map) press shift+prnscr and switch to 15KHz (!)
d) press space 1 or 2 times
e) press prnscr to return in vga mode and play the game

enjoy!

ehm... for all, there are two rules to clarify:

(a) OCM-PLD Pack 2.4 --> SD-CARD makes boot with "MSX2 BIOS" only (as 1st file, 256kbytes)
(b) OCM-PLD Pack 3.0 --> SD-CARD makes boot with "MSX2+ BIOS" only (as 1st file, 384kbytes)

Regards!

Hi!

Been testing some more. Most of the (very short list) software for 2+ seems to work fine.
But i found a problem with Music Module. Appart that it sounds too low now (i'm almost sure it was louder before..), seems that it skips almost all the MIDI-In data. I mean, if I send MIDI data to the Music Module, thru the DIN connector, I lost 99% of the data. From time to time some note plays, but that's all. Checked the same soft+Music Module in my F9S just to be sure my Music Module didn't crash, and it worked perfectly.
I was sure Music Module worked properly before, as i used it on a tune. Any idea?

can you check the cpu clock if 3.58MHz? and if the external audio connector work fine? which was the previous firmware ?

By MsxKun

Paragon (1124)

22-05-2011, 19:11

You got mail.
Anyways I tested with cpuspeed at 3'58mhz cpuspeed /a. Audio conector is the usual one. Internal Msx Music sounds ok, also PSG.
Previous firmware was 2.4, but I didn't test Music Module with it. I used it with the default one, the one it comes when I bought it.

Ok... If I put the BIOS on SD-Card, the cartridges work at first boot. If I remove the SD card, cartridges doesn't work at first boot and I need to reset the 1chipMSX...

Weird...

Trying to reflash again...

It doesn't work always. With MegaFlashSCC+ it seems to works at first boot, but Goonies'r'good enough or Hamaraja Night need a reset.

USAS, Nemesis 2, Vampire Killer or Penguin Adventure work at first boot, even without SD. I'm starting to think the problem is on cartridges and not on firmware...

Something weird is happening here. I can't flash MegaFlashROM SCC+, because the opfx program doesn't find it. I tried to downgrade to firmware 2.4, and the same: MegaFlashROM SCC+ not found :'(

power-off-on, power-off-on, power-off-on, power-off-on, power-off-on, without SD-CARD.

Sorry, all ok here.

@MsxKun: please, can you check with PLDs v2.3 and v2.4, DIP-SW5 = ON and Music Module on Slot-1........???

Music Module bug to fix on the next release:

- Sample Kit don't load with tMSD enabled!

By KdL

Paragon (1450)

30-05-2011, 00:16

Beta5/RC2 --> tMSD fixed --> 3.58MHz to 5.37MHz autoselection (insteed of 3.58MHz to 10MHz).
Better compatibility at price of less speedup.

e.g. you can use Music Module and CPUSPEED -B (tMSD enabled) without freezing of sample-kit (MBK) when loading.......
Warning: Music Module MBKs will be frozen again at 10MHz !!
