I have no problems sending Minty some cash over Paypal, guy seems legit.

You could also pack mine and Jake's into one bundle if it saves on delivery, we live quite close together and it's about time we went for a pint.

Please put me down :) This gets me very, very excited! Are you still working on the MD, Matt? I have not looked at any of your Blog entries for a while but have you done any more on the sound or anything else? Yep, still on it, just haven't typed up anything about it in a while. I'm sure with a wor...

I've been keeping my eye on this for quite some time, it looks very exciting! Are they available to buy assembled yet, or do I need to brush up on my electronics then order the PCB and components?

I'm planning to have integrated source editing and compilation in the future Yes, yes, yes, this! As much as I adore my MegaCD development kit, it's a bit of a pain to set up every time a have a dev session! An emulator with source-level debugger that I can run on Windows 7 means I can make games o...

A blog of my experience learning 68k Megadrive programming

Hi! For the past year or so I've been learning 68k assembler on the SEGA Megadrive, and I've been blogging the whole learning process in the hope that someone else would find my ramblings, shoddy source code and eureka moments useful when trying it for themselves. It covers initialisation, some basi...

Yes, nice + clearly written tutorials you've made there! However I would recommend using something like VASM ( http://sun.hasenbraten.de/vasm/ ) which is still maintained/bug-fixed, and has lots of nice features that the ancient & now obsolete SNASM assembler lacks (not to mention it's more compati...

Yes, this works a treat! I've limited the ramp-up range to between 0xC and 0x5, and it sounds very soft. I take it any PSG values get applied immediately, instead of waiting for the next polarity flip? Would it be possible to time a change so that it coincides with a flip, or could we not achieve ti...

Yeah, there's that too. Is this a lost cause? I'd like to be able to create "softer" notes but so far this chip doesn't really allow for it.

Ramping up the volume on the PSG causes artifacts

Hi all,

I'm implementing a volume fader on the PSG (gearing up to writing software envelopes) but with only 16 possible attenuation values there's noticeable "stepping" when ramping it up over 1 second or so. Is there any way to avoid this? Any tricks?

Cheers
