Wow!

Good work

New episode: Control Panel, DESKTOP.INF, GenST2, MonST2, and more!

Disable the key click in assembly language on Atari ST

Gorgeous. Hats off

Nice.

BTW, the dialog can be closed using the Return key, as usual.

Really excellent!

Beware: classic USB joysticks use the standard HID protocol. Xbox gamepads use a different protocol. And Playstation ones are also different.

Very good job, Thorsten In my binaries, I prefer to stick to the old binutils 2.30 (last official support for m68k). But your work is very useful to keep up to date anyway. Maybe at some point that could become the only solution.

Excellent

Brilliant.

When using ST-High video mode on modern VGA monitor, the image is aligned on top and there is a big black border at the bottom. I guess this is because the ST outputs a 640x400 signal, while VGA monitors expect 640x480. After looking at overscan techniques there , I wonder if it would be possible to...

You should also avoid jsr/rts, as they use the stack for return value, hence slow memory accesses.
As an alternative, you can use a register as for return value. i.e.:

Additionally:

You can also use (a1)+ to increment pointers when possible. So you can avoid the offset in next instruction.

Also, for actual data, no need to use intermediate registers. You could just do move.l (a0)+,(a1)+ for example.

First, be sure that your assembler really optimizes 0(a0) to (a0) (use debugger/disassembler to check that). Or to be safe: just use plain (a0). Then: clr.w d0 followed by or.w 0(a0),d0. Useless. Just use move.w instead. So you can even remove the clr. Also, as you use all the 4 planes, you could ce...

Do you have a guide on setting up RPI with gcc cross tools for Atari? I set up a fresh RPI4 with a fresh install if RPI OS 64bit to see if I can run the updated AGT framework on that I occasionally build the m68k-atari-mint cross-tools for Ubuntu ARM (includes arm64 and armhf). Pretty easy, I just ...

Is there any official FPGA update to fix that?

mfro wrote: ↑Mon Jul 18, 2022 10:40 am Not a hardware limitation, but one oft the many FireTOS oddities. Using EmuTOS, you *can* set all Videl resolutions (and using fVDI, supported extended resolutions as well).

Yes, with EmuTOS you an set any VIDEL resolution, but some of them look buggy due to FPGA issues

New episode:

Display a monochrome picture in assembly language on Atari ST

IIRC there is a bug in GCC 4 when it generates STABS debug information. This is the format of debug information used in old a.out binaries. I never investigated what really happens in GCC, and GNU people don't care about a.out stuff anymore. Maybe that's just a misconfiguration, or a more serious is...

For sure HP LaserJet P3005dn has a ColdFire V5, I saw it with my eyes. It has the same form-factor as the FireBee's ColdFire M5474 (V4e core). Is it pin-to-pin compatible? No idea.

To my knowledge there were no ST with SECAM. Actually, I’m not even sure version with modulator were sold here. By the time the ST was released, SCART connector with RVB was mandatory on all TV sets and all the French ST I’ve seen so far were PAL using the RVB out (there is no CVBS neither ). Blank...

Another great video Vincent. Thankyou! :) Thanks :D Great tip about the 'crashing only with 4MB' issue. So I wonder what happens when the CPU tries to access a legal, but non mapped/used memory location? Is it literally ignored? Yes, if for example you have 2MB installed, then writes to the 2MB-4MB...

Finally, new video tutorial!

Really excellent job
