Re: Donkey Kong: Walking Sound Hack?

I haven’t tried the latest core, but I can do those jumps easily on my real machine, but struggle to pull them off on MiSTer.

Re: Ms. Pac-Man Oddities

Both of these are normal behavior (i.e., they happen on original hardware). The blue/red maze is some sort of memory bug and the pass-through is when both Ms. Pac and the ghosts arive at a location at the exact same time.

Re: Donkey Kong: Walking Sound Hack?

This is a very small issue. I have 4 DK PCBs. They’re all slightly different, but I’ve replaced just about every component in the analog section of one (chasing a bug) and, while the sounds changed, it was more component to component variation than age related variations. 20% spec variation over several components will add up. That being said, I b...

Re: Donkey Kong: Walking Sound Hack?

- how has 40 years of time affected original parts - or has the machine been kept well-maintained ? To me, this can be the biggest one. Do we want to recreate what a Donkey Kong board sounds like today with 40+ year old components or do we want it to sound like factory new. Is there even a difference? This is a very small issue. I have 4 DK PCBs. ...

I’ve used an original stick with mame. There is a way to wire the rotary part up with a bunch of diodes and an ultimarc encoder, which I forget exactly how to do. Very cool - love this game.

Re: Donkey Kong: Walking Sound Hack?

BTW, can someone more skilled than I (that’s anyone who can actually work with this code) check on the digital music code in Mister. For some reason, the rhythm/notes of the post board song is off.

Getting the analog sounds right would be a miracle, but it won’t be that great overall if the digital music is still off.

Re: Donkey Kong: Walking Sound Hack?

I commented on the original PR that got merged. I'm in the camp that was slightly bothered by the samples in that they can't reproduce the random nature of how the walking sound is actually produced. I'd think though that anyone sensitive enough to want an improvement in the existing walking sound would not be convinced that this is an improvement...

JROK ended up using samples. He implemented the SC-01 in FPGA, but concluded that without knowing the precise analog components used to mix phonemes, the result just didn't sound right.
Good to know. Thanks!

Re: Donkey Kong: Walking Sound Hack?

Just tried it out! It definitely sounds better. I checked an old MAME video on YouTube and indeed it sounds sequential. I think it's still a bit off from a real board, but it's a big improvement, thanks for making this happen!! I totally agree, it sounds alot better, thank you so much :D However, I get some weird issues. It doesn't work to reboot ...

Re: Donkey Kong: Walking Sound Hack?

If someone had the skills and was really in love with DK, they could do it, but bringing analog to the digital world is pretty complex. Multiple randomized, well sampled samples for the analog sounds is probably the answer for now.

Re: Donkey Kong: Walking Sound Hack?

Although I want it fixed, I don't particularly like the idea of modifying a core (using wav's) to fix a sound issue, even if the original implementation did it. I'd rather a core be implemented 100% correctly true to original hardware and have a solution outside the core. For example, I'm curious to see if the audio coming out of the MiSTercade (w...

Re: Current arcade core with the most useful CRT test patterns?

Neogeo has a test pattern rom. That being said, I find the core to be a bit dim overall, so you may need to adjust a bit once you’re done.
