Re: Request for help in organising/releasing source code

If you think it appropriate Richard, your project could be easily added as-is to the stardot GitHub organisation alongside other open source community projects. Github is actually quite straight forward to use once you acquire a few bits of know how, and I'm continually impressed with how collaborat...

Re: Repairing a dead A310 power supply

Resurrecting this thread in the hope some kind folks could help out a non-hardware-techie type like me with fixing an old A310 I bought on gumtree. The seller wanted to show me it working, but when he did, a bunch of smoke came out of the machine so he offered it for just a tenner - bargain! :D So, ...

Re: Happy Mrs Chicken!

Having worked on official Peppa Pig games, I can say that they do endeavour to protect their copyright but not that aggressively - there were at one point a whole slew of knockoff Android PP apps. Realistically, rights holders aren't going to eat the cost of enforcing against hobby projects like thi...

Re: Music software?

Definitely great to hear that there's interest in new music for the old Beeb. I am noodling away at a 6502 music player for Deflemask DMF files, but it may take some time! DMF is not a very compact file format, and cant be used 'as is' because it is gzipped, so some sort of file format conversion wi...

Re: SN76489 best sample playback?

The variant in the Master System and Game Gear has a 16-bit shift register rather than a 15-bit, but it's embedded into the VDP so it's not necessarily drawn from official blueprints. This is actually a good improvement by Sega for the MS/GG, since it means that the periodic noise is exactly 4 octa...

This SMS Power link has been extremely useful for me over the past couple of years, while I was messing with sound chip things.

Yes, the SN data sheet says this: 7. DATA TRANSFER The microprocessor selects the SN76489AN by asserting !CE (active low). Unless !CE is asserted, no data transfer can occur. When !CE is asserted, the !WE signal strobes the contents of the data bus to the appropriate control register. The data bus c...

Re: SN76489 best sample playback?

There are some unanswered questions -- are the assumptions correct? Why does changing the volume (of a square wave) let you play back samples at all?

Re: New Disk Image Editor

Sounds great David. It's been brilliant to see how much community effort has enhanced open sourced projects like BeebAsm and B-Em.
I actually much prefer c# over c++ for getting stuff done quickly. Plus I believe .NET apps can run just fine on Mac/Linux using Wine.
