Another excellent looking schedule. I'll be there for the whole day, please.

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

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

Here are a couple of quick tweaks for the current head (410 commints). beebwin.cpp line 1617 case MM_JOY1BUTTONDOWN: case MM_JOY1BUTTONUP: JoystickButton[0] = (uParam & (JOY_BUTTON1 | JOY_BUTTON3)) != 0; JoystickButton[1] = (uParam & (JOY_BUTTON2 | JOY_BUTTON4)) != 0; Instead of buttons 1 &...

Just tried your latest update, and the music is a lot better! I like Micro Rally-X for the title

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.

Oh, interesting! I'm actually working with someone on improved joystick support, including keyboard mapping and per-game mapping files:

https://github.com/stardot/beebem-windows/pull/87

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) ......

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 ...

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...

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...

Hope it's not too late to join in... I got to level 2! 27,977

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...

I have added some extra comments not in the version in GitHub. [...]

Thanks! I've just started looking at this, so I've tidied up the code to make it a bit easier to follow. I must admit, I've not read through all the comments in this thread yet...!

Sorry for being a bit obsessive. I now see i was 1 pixel too short in the overall cell. #-o this is perfecto! and what I would like the emulated mode 7 to look like. :wink: 512x512.GIF I love it :lol: I haven't looked at BeebEm's mode 7 emulation in any detail, apart from how it renders on a charac...

Wow, this another excellent lineup, thanks again for organising! I'll be there for most of the day

Thanks for all the suggestions, there's lots there to look at for the next version! To help me keep track, I've captured them as GitHub issues: https://github.com/stardot/beebem-windows/issues

The demos you've given at the Thursday dev evenings are really impressive, looks like a great game. I'd be happy to test it, I only have a BBC B so would have to use an emulator.

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. I was thinking that line 1890 should be 1890 IF DX=0 AND DY=0 THEN GOTO 185...

Did you make any more progress?

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

Thanks Mick! Yes, I'll take a look at the Mode 7 issues at some point. I knew about FireTrack and The Shapes Game, but wasn't aware of the problem in Twin Kingdom Valley. I also didn't know about Wizzy's Mansion. The light pen issue with Pharoah's Curse was fixed in the previous version (BeebEm 4.15...

I'm playing catch-up again... for me, level 7 is the new level 5

Not sure I'll beat this score before the deadline... 2511

Re: VDFS in BeebEm, is this a thing? I can't see anything in the documentation or a ROM image to load (I assume it would need this?). Any pointers appreciated...

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

Thank you Ed for running the competition, it's always good fun. A close run for the Deathstar high score there...!

There is currently a ticket open against beebem to fix analogue support on a Microsoft Xbox 360 controller. Mine works fine in beebem 414 and 416 on win 7. Can anyone tell me if it works on win 10? My concern is that the proposed change is to move to xinput which only supports 360 compatible contro...

Thank you all...

Great release, and good to see some MAME code back in there

MAME was also a great reference for the 6502 opcodes. I'll be looking at the TMS5220 again soon, I haven't figured out how to integrate it with BeebEm's audio output code yet...
