Guys, just a head's up; I plan on changing how the Yamaha is detected, using some ideas that RevEng suggested here.

Thank you Bob. I haven’t changed the header yet, as I was hoping an updated ROM would be available to handle this. Thanks again.

Thank you :) It was a complete surprise to me when I got the e-mail... Like I said in the other thread, I was absolutely sure that Millie & Molly had won.

Congrats on the win.  Fired up Pac Man 40 on my Dragonfly a week ago for the first time, and the sound blew me away.  Easily the best port of Pac Man ever, for any 8-bit game system.

Thanks, guys :)

 

I need to do two things yet: revisit the Yamaha detection and write a new manual.  @Atariboy2600 has agreed to do new artwork for this one, and @Nathan Strum has agreed to do the artwork for Galaxian once it's ready. :D

I'm in as well.  :)

So I have a potentially-dumb question. If/when carts are ready, will each cart need its own YM2151 sound module? I mean, it's obviously technically possible given the way the Dragonfly works and the cartridge-audio line on the 7800 cart connector. But do any of the existing homebrew cart PCBs support the YM? 

 

With the state of the XM completely out the window now that Curt has passed, this probably needs to be addressed by someone with the electronics skill to design such a cartridge board, if they haven't already.

In an interview with @PacManPlus, I proposed to design such an adapter, but you have to wait for the YM detection problem to be resolved.

Can you detect YM with IRQ? All you need to do is set the appropriate register in YM and check if an interrupt occurred.

Hi Guys:

 

Just made this change.  Good news, The Dragonfly can detect the Yamaha without playing with memory settings.  Bad News, the emulators can't, and default to TIA sound.  (Though I'm proud of my TIA sounds) :P

 

Attached!

 

Thank you RevEng - your code worked! :)

 

Thanks, 

Bob

I admit I am no Dragonfly expert - but would it work with YM with just a regular 7800? Sorry if that sounds like a dumb question but if I need some new module for the game I am willing to do it.

I recently found a bug in Ms. Pac-Man Plus. When I finished the Apple level, I surprisingly finished the maze while the second the maze disappears, the maze is aligned differently.

No - just like you would need a Pokey to get Pokey sound, you need a Yamaha chip for Yamaha sound.  While there currently is no cart board that supports this, I know @rj1307 mentioned he was going to work on a plug in 'pass through' module for this. 😊

Wow, nice catch!

I think I know what causes that: when I make the board go "invisible" ,  Instead of turning the color of the board black (which I cannot do because there are  other objects that use that color), I make the character mode widths 1, and move them off-screen.   It looks like if you finish the board that way, it never gets moved back to its correct position. That should be an easy fix.

 Thank you for reporting it!

Bob, thanks for all you do! I'm just lovin' this game, and I say it is THE best version of Pac-Man for any 8-bit system!

 

Since the above change was made, I'm unable to get my CC2 to recognize anything besides Yamaha sound. Of course, the CC2 has no Yamaha capabilities, so it now plays without sound. The previous versions would identify the TIA and default to TIA sound (which I agree is AMAZING)! I've tried almost all of the 128 kB banking files to no avail.

 

I know it's basically old and unsupported, but is there any chance of compiling a version where the BIN recognizes TIA for loading from the CC2?

I don't know what detection is at the moment, but the chip is visible even with Yamaha turned off (Chip Enable signal = 1). This makes it impossible the TIA sound from starting.
