Re: Wires? Pah.....

Maybe as it is supposed to be a disk image, it is only transferring whole sectors (256 bytes) or possibly waiting to read a batch of 256 bytes before sending. Either way, beebasm could pad to a whole sector without bloating things too much or it could be padded afterwards. As there are probably many...

Re: New version of Scramble for the beeb (going well)

With regard to stack usage, why not do both ;) There are 50+ bytes near the bottom that survive everything I have tried and I rarely use much actual stack in my games :). Centipede uses &111..&16F inclusive for its High Score table, which is saved after a reboot, so it should be safe to start the st...

Re: New version of Scramble for the beeb (going well)

I've just noticed that I did remove the RTI from &D00, so an MNI would hit a BRK! What I do is: In LOADER, set the keys in &80..&85 then *Scrambl or in ROM set the keys in &80..&85 then JMP to Scrambl In Scrambl: Set top of stack to a lower value to allow a bit more room for game code (just moved th...

Re: New version of Scramble for the beeb (going well)

It is just what comes out of beebasm. I can't remember if it is padded or just as big as is needed. The file Scrambl can be loaded into sideways ram and used as a ROM (with default keys). If it is in slot 0 (back slot on a master) it will auto boot turning your beeb into a dedicated scramble machine...

Re: New version of Scramble for the beeb (going well)

I confess, I only tried it on the compact and B.
If beebem timing is correct on Mac, the non-beebem should be OK, but if it is off in a different way, it won't work, this usually shows as a black screen or pairs of repeated rows.

Re: MAME: Speech

Don't rely on my names, as they are only used ORed together and it then looks for the one that changes after a reset to decide which is which. I think the beebem code may swap them more than once, which will also hinder identification. From what I remember, the delays between sending a command and t...

Re: Reading Atari ROMs

I just had a quick look on Atari age at this thread.
Do you know if the MMU GAL is OK?
I also don't see how you can put four copies of an 8K OS in an 8K EPROM, but they say it should give the self test!
Sorry if I am referring to something that you have already investigated.

My Compact seems to have a lot of bounce on fire (which does bomb too), nearly making it auto-fire, or I have another bug. The Scram...

A cheapo HDMI to USB capture device.
Two strange things:
1.it seems to convert HDMI to analogue and then capture that.
2.on the customs sticker (from sender) they value it at 61.xx GBP (can't remember pence) even though the actual cost was £6.25!

Re: Building B-em with Visual studio

In nearly all cases, one type shouldn't be cast to another where the desired is to use the same bit pattern for two different things.
The "correct" way to do it is to have a union with both in and then use the member that does what you want when you want it.

Re: Building B-em with Visual studio

I know that I tried the allegro 5 build, but I might have just ported the new emulator bits back to the v4 build.
At one point I removed allegro etc and moved evrything to directx, but I think I fixed my issue and never quite finished the port.

Re: Building B-em with Visual studio

There have been a couple of threads about building b-em with visual studio, and it wasn't straight forward.
If you don't get an answer, I can check tonight what changes I have that are to allow it to build, but thinking about it, it is probably based on an older version of b-em.
