Re: Small LUT question

@PJW, That last one was indeed a miscalculaion (3FFF vs 3FF), sorry. From your text you say "Vicky memory map is the same as the RevB" But revB has the pallettes at 1F40 and 1F80 (I think like emulator) not 1F00 and 1F40. So either stef's published revC spec contains the wrong range or they moved. N...

Small LUT question

I've been toying with the emulator to see how vicky works and I have the following questions/notes. Hope someone can answer them for me From the Revc4 published memory map I get the following: $AF:1F00..$AF: 173F - Text Mode Color Palette (Foreground) $AF:1F40..$AF:1F7F - Text Mode Color Palette (Ba...

Re: Sound fo the IDE

Had some time and adjusted the rate and time for buffer request to the virtual adlib. Rendering the samples to disk so mistakes with the audio pipeline where excluded.
Both songs now sound perfectly

Re: FAT 32

Sorry! I created some confusion in my question. I was talking about the FoenixIDE and IDE as the hard disk interface at the same time. That's not helpful :D In your screenshot I see you are testing your fat code in foenixIDE (as in development environment), since the foenixIDE had no IDE (harddisk i...

Re: Sound fo the IDE

Yeah, I have an idea about that but I have not been able to test it out yet. At the moment I am feeding the "chip" in one thread and yanking out samples to an audio stream on another thread. I thought I could do this because the opl2 is a continuous generator (it does not stop/change the sound witho...

Re: FAT 32

It is great work, but I'm not sure you should remove the ch376 (and I am not saying that because I was working to implement it in de IDE :), things change). The ch376 is a somewhat low threshold chip, "easy" to get going and if people want to do stuff or experiments without the standard kernel, it a...

Re: Foenix IDE

You could build something like this:

But without the PI in it off-course. You can get the button, sticks and printing everywhere these days.

Re: Sound fo the IDE

Did some more fiddling. tested playing two DRO file. phemopop.dro sound almost fine. Maybe quite acceptable when working on a simulator. However strickeforce.dro sounds quite bad. As a non musician comparing it to other players out there it seems that strikeforce is a much faster song. It almost fee...

Re: Sound fo the IDE

Did some further tests today. I found some information on doing a simple frequency sweep on the opl. Turns out that actually works. Got a nice stable beep in my speakers. Now I have to figure out what part of the emulation fails when actually trying to play opl music files. So more tests to do. My o...

Re: Foenix IDE

In answer to sduensin. I have used the wdctool with the foenixIDE and it works... I only did some very crude tests to see if I could read register and respond to interrupts. (all without the kernel loaded) For the foenix ide I used: wdc816cc -ML simple.c wdcln -HI -V -T -P00 simple.obj c0l.obj -LCL ...
