Re: Frak! - PC style for testing (Private invite to regular HSC competitors only)

Hi Nick, On SpinCycle,I typically go clockwise round that first part (down, yoyo, left, up, right, down, yoyo), so haven't thought about those jumps being too one-way. But you're right, so I'll see if I can tweak them slightly, it shouldn't change the timing or outcome of the level at all. I see, th...

Re: Frak! - PC style for testing (Private invite to regular HSC competitors only)

Overall, this is looking really good, although with some minor frustrations. I've got a few points of feedback, but in general I'm enjoying figuring out the levels! I even got a speed medal for LoopDLoop :-) (2:04) On SpinCycle, perhaps this is intentional, but I find myself missing these jumps too ...

And now for some play time.
So glad to hear you've got it all working! =D> I have a similar setup with RGB to HDMI, noise killer, Yarrb2, AtomMMC. It's a great combination. Enjoy!

Re: PunyInform and Ozmoo

No problem, I'm glad that's all it was! Do you think this is something that "should" work? I don't know what that ROM does or how common it is or how much it inteferes (deliberately or accidentally) with the running system. Ozmoo is mostly written to use legal OS calls so it shouldn't really confli...

Re: PunyInform and Ozmoo

Is this not due to the long-standing bug in Win BeebEm that will often misidentify a totally valid .SSD as "a DSD in disguise" (i.e. Win BeebEm mistakenly thinks that the valid .SSD is a DSD with the wrong filename extension (".ssd") applied)?: https://stardot.org.uk/forums/viewtopic.php?t=9815#p11...

Re: PunyInform and Ozmoo

Problem solved! It turns out I had a ROM installed - userPortTools.rom - that was causing the issue. Remove that and it's all fine. Sorry for the false alarm! I do recommend updating to the 4.15 release version, rather than using the beta versions, as there have been lots of fixes and improvements s...

Re: PunyInform and Ozmoo

You could break into the debugger and see where it's stuck. When I had some problems with MAME and b-em this helped to show whether it was stuck in Ozmoo code or in the filing system. If it's Ozmoo code if you can report the machine configuration and the program counter I might be able to offer som...

Re: PunyInform and Ozmoo

I'm trying out hhggZ3.ssd in BeebEm (to test the new Paste command) and wondering I've uncovered another emulation issue. Following the walkthrough, it's fine until step 7: "GET ALL", where the game loads new data from disk, at which point it outputs just "telephone: You pick up the receiver" then s...

Re: Yarrb - redesigned

The problem is still there when I killed in Asteroids, but other newer games, like chuckle egg, run ok . I wonder if everyone has the same problem with this game on hoglets menu A. Could someone check this game for me to see if it is an existing problem Asteroids is working OK on my Atom + Yarrb2.

Re: New version of PacMan (PuckMan) for the BBC Micro

I suspect it has a bug in the BIT zp instruction and the AND part. Well, there is a bug in BeebEm 4.14 (but not in those instructions). The problem was with address wraparound with LDA (zp),Y. There's more info here . Running under the debugger, I can see that PacMan executes a LDA (zp),Y that gene...

Re: Yarrb - redesigned

Hi Dave, I hope you can get your Yarrb2 board working. I worked out the values from the Yarrb manual, section 3.1 and 4.1.2: 3.1 Switching CPU clock frequency You can switch between 1, 2 and 4 MHz in your software. Bits 6 and 5 of #BFFE let change you the frequency: bit 5: set -> 4 MHz clear -> 1 or...

Re: Yarrb - redesigned

I've just installed a Yarrb2 board into my Atom, and I was experiencing the exact same issues as DaveLecky. The mod suggested by cjm seems to have solved it for me :D

[Edit] The board is working fine at 1MHz and 2MHz (using ?#BFFE=70), but if I select 4MHz (?#BFFE=38) the Atom hangs.

On real hardware, the mode7-3c00.ssd test works correctly in OSMODEs 0 & 1, and displays the message 'We're now in mode 7....'.
In OSMODEs 2 thru 5 it reports 'Sorry, BBC B Only'
Thanks, Ken. BeebEm now works correctly, and this fix will be in the next release version.
