+Vorticon Posted December 17, 2018 Share Posted December 17, 2018 IIRC the release version of the FinalGROM maxes out at 1 MB. Ah too bad... I really wanted to see how it plays on real hardware... Quote Link to comment Share on other sites More sharing options...
Omega-TI Posted December 17, 2018 Share Posted December 17, 2018 I wanted to check it out in Classic 99 but all I get are beeps after I start the program. Dunno why yet, but I'm out the door for work now and will have to mess with it later. Quote Link to comment Share on other sites More sharing options...

Tursi Posted December 17, 2018 Author Share Posted December 17, 2018 Just for sake of note: I will not be checking to see who wants one when I have them ready. You'll walk up with cash in hand (well, virtually). I just wanted to share the status and leak a demo. Feel free to continue posting, but just don't set the expectation that I will check back here. I should be able to take a video on hardware soon, I just wanted to get a bit more in before I paused to do that. All the pieces have been independently tested though. 4 Quote Link to comment Share on other sites More sharing options...

Tursi Posted December 17, 2018 Author Share Posted December 17, 2018 Turn off F18A emulation. I do all my testing with F18A emulation. But make sure you're running a version new enough to /load/ an 8MB ROM. The debug log will tell you if it truncated the file. Quote Link to comment Share on other sites More sharing options...

The debug log will tell you if it truncated the file. I remember we talked about this for the attract demo. This is true as of 399.03, and just tested with 399.04. If I turn off F18A emulation its runs fine. There may be other options causing this, as well. Wanna have a look at my ini? Quote Link to comment Share on other sites More sharing options...

Omega-TI Posted December 18, 2018 Share Posted December 18, 2018 Going from 399.003 to 399.04 did the trick without having to exit F18A mode. Thanks guys! 1 Quote Link to comment Share on other sites More sharing options...
+OLD CS1 Posted December 18, 2018 Share Posted December 18, 2018 There has to be something else in my Classic99 settings which break this for me. If it is F18A-enhanced then I definitely want to see that. EDIT: Found it: Turn on GPU interleave. 2 Quote Link to comment Share on other sites More sharing options...

The GPU code never sleeps, so the round-robin config will just appear to lock up in Classic99. Good call! Quote Link to comment Share on other sites More sharing options...

Asmusr Posted December 18, 2018 Share Posted December 18, 2018 Hi Tursi, this is a great demo and I'm particularly impressed by the sound quality in Classic99. Please remind me how the audio playback is done so I can think about whether it's possible to emulate in js99er.net. At the moment I'm only supporting changes the the PSG registres roughly every VDP frame, which is way off for sampled sound to work. 2 Quote Link to comment Share on other sites More sharing options...
Shift838 Posted December 18, 2018 Share Posted December 18, 2018 i'd be in for one too! Quote Link to comment Share on other sites More sharing options...
Tursi Posted December 19, 2018 Author Share Posted December 19, 2018 Hi Tursi, this is a great demo and I'm particularly impressed by the sound quality in Classic99. Please remind me how the audio playback is done so I can think about whether it's possible to emulate in js99er.net. At the moment I'm only supporting changes the the PSG registres roughly every VDP frame, which is way off for sampled sound to work. That's what I used to do too. I stole an idea that a friend of mine used for his Atari 8-bit emulator. Basically, just generate a frame's worth of audio at a time. In Classic99 I didn't want to mess with the existing channels much, so I set up an extra buffer that I called the DAC buffer. If a channel's frequency is set higher than a cutoff value, I treat it as a DAC output instead, and fill the DAC buffer based on the cycle count and volume level. (As a bonus, I also use this channel for WAV file playback for cassette and the single-bit ticks from the cassette audio gate, like Perfect Push uses). This isn't 100% accurate, of course, because we lose the high frequency "carrier" of the square wave, but the real thing doesn't sound much worse (and we'd need 90-100KHz of audio generation to reproduce it accurately, only to find that the TI's audio out circuit muddies it anyway ). You'll find the handling code in sound.cpp, updateDACBuffer(). It takes in the number of CPU cycles and uses that to decide how many samples in the buffer to update. At the end of the frame sound_update() merges it in with the generated output for playback. 2 Quote Link to comment Share on other sites More sharing options...
Omega-TI Posted December 19, 2018 Share Posted December 19, 2018 At this point I have no clue what I'd use it for, but this special cartridge (new hardware) that is required for Dragon's Lair... will it also be sold separately in the future for others to experiment with or fill up?

Not by me... I'm not a salesman. That's why I need someone to do the productization side for me Anyone can make their own, of course. The 128MB flash chips were getting harder to find, but last time I looked the (compatible) 64MB flash was still common enough. It's non-trivial, though, since you have to program the flash chip before you solder it down. That's going to be my biggest risk during assembly. You could make a test board like I did with a socket, but the flash pins are pretty fragile and only good for a dozen cycles or so, if you're really careful. I broke a few just testing back and forth. Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted December 19, 2018 Share Posted December 19, 2018 Tursi, I have a few SMT sockets of the right type for this if you need one to build a test board to verify the chip works perfectly before you solder it in place on another board. . . 2 Quote Link to comment Share on other sites More sharing options...
