Re: High Score Challenge Season 15 - Rd 5 - Tempest

It's taken me a while to beat my previous score, and only a small improvement. I've no idea how people are managing to get to 100K+. My best so far: 34,500

Re: High Score Challenge Season 15 - Rd 5 - Tempest

I always thought this was a good arcade conversion, but does it stand the test of time? I used to play this quite a bit... 29,900

Re: High Score Challenge Season 15 - Rd 4 - Blagger

Obviously inspired by Manic Miner, but the slooow jump (and sound effect) and the walk through walls bug let it down a bit. Here's my starter score, up to level 3... 3030.

Re: Possible new version of New Rally-X for the BBC Micro

From my point of view, as someone who is vaguely musical ... x2 is OK but lacks the bass notes, x3 the harmony isn't right (wrong notes), x4 (vgm_test) is the best of the three, and pretty good. I suggest adding a delay after the end of the intro tune before the main game tune starts (x2 and x3) ......

Re: Latest version of BeebEm

I haven't looked at sound yet. Sorry, I did see your message yesterday... For the frequency fix, I see your RallyX test (X3) sends freq=0 so I can use this to compare with a real Beeb. The other thing BeebEm does emulate yet is the 32 clock cycle transfer time sending data to the sound chip. Do you ...

Re: Latest version of BeebEm

Just catching up on the discussion so far... BeebEm has an extra border around Mode 7 which is not there in the other modes, so they are not taking up the same amount of space on the PC screen. Apart from making the font look a bit narrow, this would be problematic for anything which dynamically pro...

Yes, I think what's puzzling people is why that looks smooth and the sceenshots don't. Chris said " StretchBlt() is used in the same way when you use Capture Screen " so maybe that's true even if you've selected DirectX or DirectDraw as the Display Renderer? That's right, Capture Screen u...

Re: Latest version of BeebEm

So the test at the start here is intended to optimise the case where all the pixels in the line (one row of a character) are the same colour, either all black or all white. But, for the all-white case, it is looking at the row from the font, not the character code, and the font is 12 pixels wide so...

It's as if as soon as the main window loses focus it just stops. Is that how "Freeze when inactive" works?
Yes, that option means that the emulation stops any time the main window loses focus, which includes opening the debugger. I'm not sure why that's the default setting but it is...

Re: Debugging thread for DomB, ChrisN, PhilM & Tricky

There's two ways I can see that the program might hang during initialisation (PROCsetsquare). The first is where DX and DY are both 0, it never makes any progress, and because there's ON ERROR at line 1810, pressing Escape goes back to the start - but next time round might be fine, as long as DX and...

I think line 1890 should be 1890 IFDX=1ANDDY=0THENGOTO1870 That bug would only manifest itself where all the letters in the word were the same I think as when DX=0 and DY=0 it would (I think) try again later in the routine.

Not a bug fix, but it might help see what's going on to change line 310 to "." instead of CHR$(...).

It's not (yet) a thing. jgharston contributed an initial implementation, but it needs a bit more work to get it ready to release.
