yes, it's what I noticed... it's very difficult to find correct timings which work for every games considering latencies, i implemented vdp access latency on vram writes, as specified in Genesis manual, and it corrected screen flickering in Chaos Engine for example, but for others timing, it's very...

Hi Stef, yes i'm the one who bothers you last year with the GP gamecube's port , I managed to solve my previous problems and also improve overall compatibility and functionality... thanks for having made Gens open-source :wink: My last problem is with Hint occurence: if this should happen before hb...

I uploaded my Stereo player. Mine only does "iiiiiiii" on the real thing, YM2612 really hates switching speakers, If I played 512 samples, I could hear some pretty shitty sound. 4 samples is the best, more is good too but not less than 4. I dropped my audio converter and did a little trick in softw...

Hi, I'm currently working on the compatibility improvment of my Genesis Plus port and find this board, so I join your for a few questions ; I found that some games (i'm actually testing together Skitchin', Lotus 2 Recs and Legend of Galahad) are very timing sensitive, especially regarding H & V int...

1 sample sounded awful, because if you change speaker, previous value will be outputted aswell, and stereo effect gets little too mono. I made a special audio converter for that. I need to find and refine the source. BTW my SRAM cart didn't fry and I tested my MSETEST on it and I can say, YM2612 li...

I wrote a stereo sample player these 2 last days. It's worked perfectly with Kega but not with Gens :p On real hardware, it was first just doing silent... After i figured some weird stuff about the YM2612 chip, i was able to get it up on real hardware, unfortunatly the used trick doesn't work becau...

Welcome on the board ! It's always appreciated to have a new member here :) I'm glad to hear you're using my minidev kit, i hope you can use it without too many troubles, don't hesitate to ask for any problems you can meet ! If you're insterested by sound stuff, you should have a look on this topic ...

ah ah!! 8bits gave more hints, I didn't see it like this when I first read Stef post ;) I got the point but as TmEE said, it will drop the DAC freq :( If I add FM switch + FM play + (PSG switch + PSG play)*3 on loop..I'll have 1Khz DAC :( or perhaps here is the real reason to optimize more my DAC d...

ok...DAC is good but I now have a problem with all the only possibilities I saw : di / dac stuff / ei which is impossible :( A trick I learned from ColecoVision might help: When doing something that will conflict with the interrupt, set a "busy" flag. In the interrupt, if the "busy" flag is set, do...

ok...DAC is good but I now have a problem with all other... let me explain Vint : -> bankswitch -> psg data -> bankswitch -> FM data Loop: -> bankswitch -> DAC data so, as you, perhaps, can see, I'm able to play the 3 things (with DAC not at 40KHz!) my problem, when Vint occurs while I'm playing wi...

I don't understand your last point, doesn't look like the same idea than Pascal was speaking about ? 2channels, 1 at half speed, if 1st channel is 16KHz, other will be @ 8KHz. You play 2 samples form 1 channel, and when you play 2nd sample, you mix it with one sample from the 2nd channel. It will b...

8 and 16KHz, sounds interesting, but changing banks is still a real sample rate killer... My idea: play 1 sample alone, no mixing, play 2nd sample and mix it with one from another channel. Then you can have 2 channels, which one plays at half speed. I don't understand your last point, doesn't look ...

I noticed some strange behavior with the previous version (KMod 0.6 beta), for instance, i got a bug in my Z80 init code which was setting 0x2002 bytes of RAM to 0 (instead of 0x2000). In theory the address just overlap but here that just make KMod to hang. strange it hanges now, I didn't change th...

Yo stef :) Actualy, sometimes, Kmod can appear hang because your code generate too many error / second (so it flood and litteraly freeze the message box log... until its full). Are you sure it's not this problem? It was just an idea... sorry if its bigger problem than that. In fact i just realised ...
