Re: ABUG Cambridge Sept 7th-9th 2018 BOOKING THREAD

Bit random but would anyone like me to bring some video capture equipment? I can capture 720p @ 50Hz inc. audio from real Beeb hardware through RGB SCART to a HDMI PVR. Let me know before we set off at lunchtime! I wouldn't mind capturing some of my games and it would be good to capture the 50hz mo...

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

Thanks, I noticed the same thing last night. It is causes by the changes I made to support the VLSI (I think) 6845. I'm going to try to get a better understanding of the incompatibility and if I can't, I'm going to revert that code for the release and have a second "exe" that will support the troubl...

Re: Retro Hardware ARA III - Low Cost Writable ROM Cartridge - For the Electron and Master

I was also thinking about a switch, but to swap the two 16K slots over (not ROM_QA/A14 I guess). I'm happy to make a few mods if necessary, and I guess there is a spare pin on the GAL that could provide it. The reason is that when my games are loaded as utility ROMs, they will "auto-boot" if they ar...

Re: High Score Challenge S10 - R3 - Arc Pinball

The more I play this, the more I am impressed with the amount of work that must have gone in to it and I'm not surprised that at some point the author or publisher must have said "It's good enough - ship it".

Re: High Score Challenge S10 - R3 - Arc Pinball

It's taken me until now to get close to my third game's score that I though was easy and so didn't bother submitting - 19230! There is a really annoying bug, that I haven't seen mentioned, where the game just locks up when you loose the ball on the upper play-field and it never reloads the bottom on...

Re: USA spec BBC model B

Have you tried any beeb software, particularly games that access the screen directly (all mine ;))?
Are there any Hz issues? I guess RF (NTSC) won't work, but what about composite or rgb if it has them.
I know Arcadian had a USA beeb, I wonder if he still has it.

Re: Can't get Gotek Flash Floppy working. u56=USB [SOLVED]

I'd certainly agree for compatibility, especially if you already have a disk drive to replace. MMC is very convenient if you don't have a disk interface, if you move your machines around a lot (I guess, not many of us need to ;)) or if you want the whole STH archive easily accessible (until I get my...

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

Thanks,
I'm glad that it runs, but exiting is a shame.
Because I have stomped on everything, I try to force a power on reset with escape. Maybe the master needs more convincing.

Does anyone have any ideas?

Blue screen - well I do build on windows :lol:

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

Don't worry, I'll try it in my next .ssd. Files with a load address starting with &FF then the four digit address should load in the beeb and the rest (I think) try to load into the copro if present. Beebasm writes the addresses as 00.... So if you have a copro, the file is probably going there, whe...

Re: High Score Challenge S10 - R3 - Arc Pinball

I could have sworn I tried all the keys when my ball got stuck on the second level a few times, but I will try shift and all the others again.

I agree with Ed, that the return key seems like it should only be used for a stuck ball, but it doesn't work on the upper play field.

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

Thanks for the feedback, I'm glad it has no DC issues (yet!). I hadn't looked at Key clashes as I assumed that lots of games had checked and use these keys. I usually use SHIFT instead of SPACE, which is a little less convenient, but doesn't clash (at least on real HW). I hadn't considered the co-pr...

Re: RGB to HDMI using a Pi Zero and a small CPLD

If you have a scope capable of capturing and syncing to the signal!
I couldn't capture my vsync issue on my cheap USB scope if you remember.
Sometimes, it would be helpful to get a log of scan line counts between vsyncs, especially if it isn't 312/313.
