Re: Beeb816 Revival

Okay, I've updated my player to show the fps, seems my timing may be a little dodgy since the 10fps one only shows 9.43 fps on my beeb. I also added a new video this one is 160x176 pixels at 50fps, this is 13.5KBytes per frame, so it's a proper test (it's also the extreme limit of double buffering o...

If you want to test transfer performance from the tube I've created a little test, the image attached contains a working non-sound build of my smacker player along with two videos, one is the normal BBC 10fps Dragon's Lair trailer video, the other is a 50fps version of the same video, this video pl...

Re: Beeb816 Revival

It would be interesting to see how it performs with tube transfers, obviously reading from the tube and writing to video memory would have to work at 2MHz, but presumably the rest of the clock cycles for those instructions would still run at 14MHz as would the rest of the code, it would be nice to ...

Re: Compiling ARM BASIC from Source

I'll have to pull the latest version and test with my smacker player, I've got a 11MByte video file that should be a good test, it doesn't work very well trying to stream from the host harddrive but it should work when loaded directly into memory.

Re: Frontier Elite II - BBC and Pi Native ARM CoPro

Sorry, no real progress. I need to check my latest build, I was working on putting sound in, however I don't have the original atari sfx data so I was working on adding my own. I think that introduced some instability. If its working then I'll post a new Hard drive image, unfortunately it won't work...

Re: MMFS Development and Support

I use Beeb Image to create new ADFS volumes, it can create a new Empty one of any size, or can create one with an empty DOS partition.

While testing my ARM co-processor code I use smaller partitions which are quicker to copy so I've created a fair few different volumes.

Second try, haven't played this for years, definitely slower than I remember, or maybe I'm just used to games running faster in general nowadays.

Yeah. It relies on the arm Co-processor either the pi co processor, or the arm7tdmi Co-processor, which also includes BeenEm. That video is running at 10fps, 12.5 is possible although occasional frames may go over the limit (it uses a delta compression algorithm that's designed to be quick to decode...

I've gotten sound working, although it's pushed my host code to over a page (it's how 260 bytes). I was hoping to keep it to 1 page so it would load just below screen memory.
