So should this still be called Donkey Kong? It would probably be safer to rename it to avoid drawing attention. Maybe Stubborn Ape or Crazy Kong? Suggestions?

A7800x is based on the mess a7800 emulation and as was pointed out earlier it does not work under mess.Unfortunately this doesn't run on a7800x (original XBOX 7800 emulator). The screen turns green and it makes an awful racket. If I run the bin and turn off POKEY support, it runs, but silently.
Is it because it's accessing the POKEY at a non-standard address instead of like a real POKEY cart?
Your close. I write to the standard address for the pokey. The problem is that the 48k cart wasn't designed for the pokey and they have overlaping address spaces. In prosystem 1.3, any reads from that address space come from the ROM, not the pokey. It's possible that MESS emulates the pokey more accurately so when the program reads from that address space, it's reading the pokey and not the program data that's stored there. It's the inaccuracy in Prosystem that allows my hack to work correctly.
I also write to the XBOARD location of the pokey chip, which allows it to work on real hardware. But this shoudn't cause any problem with the emulators.

Here's an update. I've corrected the issue with Mario not getting to the top of the girder before the tune starts at the end of level's 1 and 2. I also adjusted the tempo of the tune at the end of level 3 to match with the arcade version. I had to speed it up because the animation was finishing too fast and I didn't know how to slow it down. Spent some time digging through the code and figure out how to modify the animation speed. Now everything is in sync.

I could throw the TIA code back in so it would work with or without the XM, but it would bump the ROM requirement from 32k to 48k. I'm not sure what that would mean in terms of cartidge cost or parts availability.
There needs to be some discussion on how this will be released and if needed, I could add the TIA stuff back in.
Perry
If there are no plans to release any other versions with a pokey on the cart, the game could easily be bumped up to 48K since the additional cost (27512 vs 27256) is virtually 0.

That's good to know. The 48k carts I've seen use two chips, 16K+32K. Thanks.

Great label Pac-man Prime!
There's one thing I need to point out about my pokey edition that I don't believe has been discussed in the PMC-Pokey thread. I had to remove the original TIA generated sounds to make space for the POKEY code. So if the game is burned to a non-Pokey cart, it will only work with the XM. Without the XM, there will be no sound, so this would technically be an "XM required" game. I could throw the TIA code back in so it would work with or without the XM, but it would bump the ROM requirement from 32k to 48k. I'm not sure what that would mean in terms of cartidge cost or parts availability.

I really like this collection. There is a bug fix on this page, along with some background info from the developer.

Auction ends tonight. Thanks for looking.

Nice Job! The game itself is still an insult to true arcade DK enthusiasts (As I felt about the Nintendo 8-bit version too, which at least had pretty graphics), but the sound makes the half-resolution and Mario's floaty jumps of the 7800 version a little more forgivable.
Many of the sounds seemed identical to the Atari 8-bit version, which I think may have been missing the music after dk falls on the rivet screen. In either case, I noticed that music was a little better than the standard 8-bit. Nice touch! I played it in Good7800 emulator, as it locked up on my MESS emu.
Thanks! I did create the music after the rivet screen but I can't take credit for the rest of it sounding any better. Might just be a difference between the various emulators. The notes, sustain, decay, etc. are identical. I also tweaked Kongs grunt a little bit and made his stomp audible. It's nice having 4 sound channels to work with.

Donkey Kong Arcade/pokey is rumored as well, but again, no official announcement.

If the Pac-Man and Donkey Kong POKEY versions get made into carts, I'm gonna get them for sure. Though wouldn't it be possible to make an almost exact port of the Arcade versions given the new Yamaha synth chip and the extra RAM?
I was under the impression that OpCode/Eduardo, the colecovision homebrewer, was already working on a full-boat DK 7800 rewrite for the 7800XM with all 4 levels, arcade exact graphics, and sound.
Kind of a bummer if that's not the case.
I thought his was for the ColecoVision and the Super Game Module... http://opcodegames.com/?cat=5
and when the XM was announced, he said he was going to be working on it for the 7800.
Looking at Eduardo's blog, it seems that he is actively working on the ColecoVision version. I havn't seen anything from him on the 7800 other than the implication he made a while back that it could be done. I'm speculating that everything that went down with his ROM's getting sold a few months back might have affected his priorities.

That's is a possibility and I have been reading up on how this ym2151 works, but unfortunately, I don't yet have an XM to play around with. I'm not going to promise anything, but I'm more likely to update PMC than DK. I just don't see the point of making arcade perfect sound for DK when it's missing a level. We can only hope that Eduardo will come through for us on that game some day.

The file currently available for download won't work with a CC2. You'd need a bin file for that. This is emulator only.WOW! I'll try this when I get some time - hopefully this weekend. CC2 settings?
I'll post a binary later for those that have a CC2 and XBOARD mod. Don't have time to do it now. If someone else know how to strip the a78 header and want's to post it, feel free.

you have no idea how much more enjoyable it is to play this game now!!! good work
but i noticed the music plays before Mario finishes getting on top of the platform to end the level? When the music stops the he's standing on on top. I tried the orignal DK...painfully, he gets on top of the platform then the music plays!
Is it a timing issue??
either way nice work!!
Thanks for the compliment. I found it unplayable with the old sound effects and music. It just grated on my nerves.
I'll see if I can figure out why Mario doesn't make it to the top of the platform. Thanks for pointing that out.

Well maybe not a surprise. I finished working on this a few weeks ago and thought it was time to put it out and let people play test it. To be honest, I haven't been able to spend much time playing it, so it might have some undiscovered bugs. Hopefully not.
One caveat though. I haven't made any changes to the graphics or game play and don't intend to. I'm sure some will be disappointed, but there is still no 4th level. It just isn't practical to do without any documented source code.
You will probably recognize the sounds if you've spent any time playing the 400/800 version. I haven't modified any of the sounds, so I'm sure there are some differences from the arcade version. Let me know if anything is glaringly off and I'll see what I can do.
One thing I have to point out is that this is only playable in emulation or on an XBOARD modded machine or on the Expansion Module. It won't work on a pokey cart because the Pokey mapping overlaps the code. I've only tested on Prosystem13, so I'm not sure if it will work on the other emulators.
Let me know what you think.
Regards,
Perry
EDIT: I've added the latest version which has some improvements (I hope) to the walking sound
and a video. I appologize in advance for the poor video quality.

they can't make OS-A/OS-B cartridges yet!
Who are "they"? You could run this on an Atarimax 1Mb flash cart if you want to play on one of the 8-bit computers.
AtariAge are "they"! But I want to make a REPRODUCTION, not put it on a USB powered cartridge!
How can you reproduce a cartidge that was never produced?

For people who want Griffey The Dog in the PAL format, help me!
You could try it the other way around. Download the PAL version and applying your hack to it.

Groovybee gave some great advice. If you have limited programming experience, you'll be much more likely to suceed if you start with a high level language first. Focus your efforts on the game design, learning how graphics modes work and structuring your code. Improvements in speed, via assembly language, will come with time. There's a chance that if you start out in assembly, you'll get buried in the nitty gritty details, become discouraged and quit.
A also second Ransom's recommendation of De Re Atari. I bought a copy on Ebay and it was worth every penny.

Looks like I'll be dusting off my game gavel account. Ebay pulled my listing for copyright violation.

Here's the Game Gavel listing.

They pulled some of mine for the same reason as well.
Yet they allow hundreds of others, even when you report them, to remain.
It confuses me as to how they are 'picking and choosing' certain items. I think my account has been 'flagged or ear-marked' lol
I hate ebay so much!
It does seem like pick and chose the auctions that get removed. Maybe it has something to do with how much revenue the seller generates.
Here's a quote from the message Ebay sent me:
"Please be assured that your listings have not been targeted in any way. We review all listings that are reported to us by eBay members or Verified Rights Owner (VeRO) program participants. "
Looks like someone might have reported me. Hope it wan't an Atariage member, as that would be very low.

My bid's in......... Don't see How I could possibly win, since I'm so cheap, But maybe I'll get lucky. If not at least I helped bump up the price...
This is one cool auction.
There was all kinds of talk about making a release of this cart. Did that happen, is it going to, does this auction have any baring on that?
I think there is likely to be a release, but my guess is that it will be for use with the Expansion Module and won't include a Pokey chip. My cart will play in a standard 7800.

If you haven't heard about this version, please see my thread in the 7800 forum.
http://www.atariage.com/forums/topic/162512-pac-man-collection-with-pokey-sound/
Which version of the code is on the cartridge? Also in the thread, you had mentioned that your cartridges was flaky ... What was it doing, is this that cartridge, did you fix it, and is there anything else we need to know about it's transgressions.
This is the latest version which is posted in the thread. I replaced the Pokey chip in the flaky one to fix it, but that is the one I'm keeping. I havn't had any problems with the one that is for sale.

Hello all,
EBAY CANCELLED IT SO RELISTED ON GAMEGAVEL
I need to make a few bucks to cover some unexpected home repairs, so I've been digging through all my stuff, I'm kind of a pack rat, looking for anything I can sell. I decided to sell one of the Pokey enhanced Pac-Man Collection carts that I built while developing the sound code. If you haven't heard about this version, please see my thread in the 7800 forum.
http://www.atariage.com/forums/topic/162512-pac-man-collection-with-pokey-sound/
The auction can be found here, http://www.gamegavel.com/item.cgi?show_item=0000435968
This auction is for the cart only. No box or manual. Starting price is a very reasonable $20. Thanks!
Perry
P.S. I ran this by Albert and Bob to make sure they wouldn't mind me selling the cart and they were cool with it.

Any Demo's for the Yamaha chip? I'm thinking the intro's and intermissions in Pac-man Collection need some YM2151 goodness.
I'm no musician but I'll do my best.
I was just wondering if you had played around with it. I'm going to start reading through the user manual this week. From what I've seen in the datasheet, I should be able to replicate the sound of the arcade machine fairly accurately. I really just need to know where the chip is mapped on the XM and how to activate it.

Surprise! Donkey Kong with Pokey sound
in Atari 7800 Hacks
Posted
There was a Crazy Kong arcade game that was virtually the same as Donkey Kong. I'm thinking it might be an appropriate name since this hack is just as un-official.
