I have a Yeno 301 XL currently on my workbench. With Sean's help from the distance, I'll try to dump the rom... it's not easy work! And then hap with his magic will do the emulation on MAME.

Patience! Many interesting things are to come.

Best,
Gerardo

Hello,

As I have already written, I have dumped these chess computers :

Chess Companion II HD6301V.
Star Chess HD6301V.
Novag Super Vip HD6301Y.
Yeno 301XL HD6301X. (doesn't look like the mondial's code, sorry Bataais)

I'm working on emulating these chess computers.

Cordially.

OMG, that almost sounds like a dangerous threat!

The problem with these 6301 devices is that I'm not able to implement all features in my old MAME version 0.220.
About 2 weeks ago 'hap' made extensive changes to the corresponding MAME drivers (m6800) regarding 'nvram',
and I just can't port them back to 0.220, because too many MAME system files are affected.
This means that these emulations play chess correctly, but do not have permanent memory (NVRAM).

Regards,
Franz

Hi,

Yes, I know. I had already read you. But if we've asked you for the romdumps and you haven't wanted to share them... I will continue as always to reverse engineer and share everything with the MAME development team.

Best,
Gerardo

Right, the overall emulation should work fine without battery-backed ram. It will do a cold boot every time instead.
In MAME, it's awkward, since (in SciSys case), you must press the STOP button before exiting. Or in Companion 2, you need to press F1 to simulate a power-off.

@Mychess: Super VIP has a fairly easy to dump EPROM, but also internal ROM on a QFP HD6301Y0. It's not like Super Nova where the whole program is on EPROM.

Hello Hap,

Do you mean that Supervip is already emulated ?

Cordially.

No, my point is, if you have only dumped the EPROM, and not the HD6301Y0 MCU, then it can't be emulated yet.

And my point is yes, I have dumped the internal rom of the HD6301Y (16 K).

Cordially.

Na dann können wir uns mit etwas Geduld schon auf Morsch's Europa, Kaplans Turbo 16K und Kittingers Mentor 16 / Amigo freuen! Alles HD6301Y - 16k Geräte.

Habe übrigens meine ROM-Dumps auch stets mit hap und Franz geteilt.. Kommt uns allen zugute.

Bon appetit!

Hi,

der CXG Enterprise S ist jetzt auch in CB-Emu enthalten - danke wieder an 'hap' und Sean Riddle.

Übrigens habe ich jetzt auch den CXG Star Chess in den gleichen Treiber von 'hap' verlagert, weil die beiden Geräte ja praktisch identisch sind. Dadurch haben sich auch einige 'starchess'-Dateien (ROM/Artwork/Plugin) geändert.

Grüße,
Franz
