Hi Zausz
  If the cart works with the original PROM but not with the EPROM that's where I'd look first. Make sure the code is burned correct; sounds like you don't have an EPROM tool so you'll need some help from someone in your area(?). Then re check the pin mapping. I'm not sure about your cart; but Sega had some carts with a external bank mapper chip and others with the mapper built into the PROM. SMSPower.org has some docs that may help with sorting the cart out.
  Another thing to keep in mind is there is no video output but there is a boot-up sound played. I don't think having the Arduino unattached will 'crash' the code but once booted you wouldn't have any signs of life, just a blank screen; with no input from the Arduino, you can't send a midi note to hear anything. So it could seem like it's crashed.
  If this is the case check the Arduino setup. You should be alright with the DB9, Littlescale used them with his GenMDM board. In fact even with the Arduino interface connected, if you have a problem with the Midi input the Master Sys may seem dead too.You could try setting up a simple circuit with a LED and resister (if you can get hold of a Logic Probe that would be best) to check the output pins while sending notes, to verify the Arduino.
Hope this helps
Yogi

SMS and GG samples are played on the 76489 PSG, set all 3 channels  Tone=$00 and feeding the 4bit Vol regs with the sample data. So while there is a little bit of a de facto standard; being software controlled, leaves the methods up to the programmer.
  At SMS Power is a good doc on the 76489, http://www.smspower.org/Development/SN7 … MakesSound

Thanks for the help yogi. In the file you sent me, there were a few problems with with two directives, but there was no way you could have known t prior knowledge of them. I only found them because they show as errors  the compiler output and I checked them against the directives list.

I'll send the new file back, although it still does not compile.

EDIT: All fixed now. It compiles and I sent it back.

Good stuff, glad I could help a little. Yea I just did a ruff edit and kind of knew there would be a bug or two. Glad you got it working!

Hi Jazz! Without a GG Flash cart, you'll need a Master Gear (the SMS cart to GG converter thing-ie http://segaretro.org/Master_Gear_Converter ) and re chip a SMS cart.

Yeah, but I meant in the source code. I would like to play with it, but when I save it and open in notepad++, it is entirely on one line.

OOOOH, I just DLed it and haven't opened the zips . will take a look now smile

This sounds like a good option.  I'm not familiar with the YMF7xx chips.  Are they in some sound cards along side the OPL3, or do they replace the OPL?  On Frequency Monster's site, I only see the requirement that it's an OPL3 compatible card and they list the SB16 and SBPro in their compatibility table.  I'm not sure what's in the computer I have in mind for this.  I think it's a Soundblaster 16 but I'm not sure yet.  Also, is FM801 multitimbral?  It looks like you may be limited to bitimbrality but it's not clear to me.

  The YMF72X line are an all in one PCI interface, PCM, XG Midi and legacy OPL3 core on the same die. There was an earlier YMF 719 ISA chip that was just FM like a SB card. I think Yamaha wanted to move into the motherboard sound market. (some Laptops have the YMF chips, and I have a Sony Viao desk top with a YMF 719 on Mobo) but with the 724 they were too late; the market was moving away from Midi and FM sound to wave/soundfont, so driver support for FM stops at XP (and getting the OPL support in XP is not plug'n'play; the generic driver doesn't support it directly).
   Yes it looks like FreqMonster 801 does indeed support SB 16 ISA cards! Cool; This is new to me, I've only played with it on XP with a YMF 724 card, will have to try it with a SB16 smile
    As to computer: Win98 or XP >200-300MHz, IIRC. There may be issues with an OPL ISA card & XP but GiveIO may do the trick.

This application is a 6 note polyphonic, 6 operator frontend for OPL3 compatible sound cards.

So yes, 6 note poly and just about every pram is assignable to a CC.:) Which sounds right with how the OPL3's voices/ops are setup.

How can you convert AdlibTracker2's speed/tempo value such as 6/50Hz into regular BPM?

You cant! ha. I have tried so many times, but the time clock within AT2 never will line up with BPM. I can get it close, but it never is exactly BPM. Its a completely different way of keeping time.

Yes it will drift. I have some songs that have about 14 channels.. so i recorded each channel separate, then played them all back together.. and they are not in perfect sync by the end. sad I also have sampled loops from AT2 and put them in Impulse Tracker, which is even more difficult because you have to figure out what is close in "tempo" pertaining to how each tracker calculates time.

Are there trackers or editors that allow you to use the FM synth on the SB16 with external midi?  What I'm thinking of would be something that allows you to edit the FM voices of the OPL and assign them to different external midi channels so you could sequence them from an external DAW through midi; no sync issues since the DAW is generating all the timing.  Does anything like this exist?  Or are we pretty much stuck with editing FM synth params and tracking from the same application like adlibtracker 2?

It'll work with the internal floppy emulation, though. So as long as you've got space on one of your two emulated floppies you're still saving to reliable flash memory.

OK, good to know. I'm new to it and probably need to re-read the docs smile

So I'm going to have a c64 in my possession soon but I'm not sure what route I should go for for running trackers on it. I'll have a disk drive, but no floppies. Been eyeing that kerberos cart for SID Wizard and Cynthcart MIDI but I don't think it supports d64 and I'm also curious about trying defmon on ntsc.

There's also that ultimate drive but that's kinda pricey. Easy Flash seems like another decent alternative but I haven't seen if it'll support d64 stuff.

So what's the general consensus? Should I just find some big old floppies or what?

Is it real to install TOS 2.06 UK on 1040 STF model? And how?

it is possible, but its much more difficult than an STe, since as I recall the TOS ROM sockets are smaller and you need a 6 chip kit. anyway, i'm not sure why you would need more memory or TOS 2.06 if you are just going to do chip music on it.

It really depends on the motherboard, the 1040 STFM I have, has footprints for 6 ROMs but only uses two ROMs. 
  As far as ram, yea it's not an easy thing to take on. Even with the Marpet upgrade, you will need to disable/remove the original DRAMs.

"For  med/color res on a VGA Monitor, you will need a scan converter and the hitch is the ST's scan rate is odd ball. "
^^ this is not actually the reason why. any 15khz interlaced scan video will need a converter for VGA, including Amiga, C64 etc etc

  Sorry, There are some multi-sync VGA monitors that will work with the low/med res signal. Even with a scan converter there are issues, so go with a model that is 'known good'.
  I just bought a super cheep composite to VGA converter from ebay; while it kind of works it's not very good. The med res display is unreadable; low res is ok but BW only. It works so-so with other video sources, some better then others. So while it didn't cost very much, ~$10, it is limited.
Here is some pages that may be useful:

   Remember one other thing, Cubase is great sequencing software but outputs midi messages for an external synth or tone generator, If you're looking for the ST's YM sound you will need qwEm's MaxYMser; it's the best.

What!?! Awesomeness. Looking over the list of parts:

NESKeytar Components:
NES
Guitar Hero Controller
Famicom Controller
NES controller
Toy Keyboard
3 Mini Arduinos
Raspberry Pi
MaxM LEDs
Midi IN/OUT connections
MidiNES / Chip Maestro

Additional Components:
Gameboy with ArduinoBoy, used for additional live midi-triggered backing.
Laser harp used in "playback mode"

Seems like the NES case is STUFFED. Would guess that the RP is controlling everything, Arduinos interface the keyboard/GH neck. The Pi sending midi to MidiNES.

Yes thats the mod I was thinking about. Don't think there is a 2 YM chip mod but if you find a schema for one please post.

And for upgrade memory for Atari STF version I should find "Marpet kit", but I can't find it anywhere. May be exist some alternatives?


Looks like Best Electronics has the Marpet kit listed http://www.best-electronics-ca.com/520_1040.htm#TT
