https://github.com/AmigaPorts/SDL/rele ... /v2.26.5-release-amigaos4 SDL2 uses only 32-bit bitmaps since this release.

@Maijestro

SDL2 doesn't use 16-bit bitmaps, probably that's the reason it works better than SDL1.

@Maijestro @balaton

Thanks for tests. I can see from Maijestro's video that the rendering was broken in 16-bit bitmap (middle one). Text looks corrupted.

Point of this exercise: I was trying to re-create a test case which doesn't use SDL1, to simplify debugging. There is probably something wrong in Pegasos-related 16-bit blitting routines (or emulation).

Please ignore the colors. It's just using some pens from 1 to 10 or so.

@QEMU Pegasos users

Please try this http://capehill.kapsi.fi/misc/BlitTest.lha and see if you can reproduce visual issues. Sources are included in case you want to experiment with window size or anything.

If it works as designed, it just prints some text and some vertical lines using different bitmaps.

Thanks in advance.

Confirmed. Seems I will need to revert back Disable/Enable.

I tried to workaround that 8ch issue sometime ago but failed. Please remember SDL is using the AHI device API. Can you advise how to fix the problem there?

I allocated larger buffers and played with offset but couldn't make it work.

Could you make the updated sources available? TIA.

@kishigo

Sony Playstation 4 and 5 controllers should work with cable.

You could try top or Tequila to see which tasks use most CPU: http://capehill.kapsi.fi/top/

This was the name of the library for years until upstream changed the versioning and started to increase the "minor" number for each stable release. https://discourse.libsdl.org/t/announcing-sdl-2-24-0/38280

It should be possible to make a soft link from libSDL2-2.0.so to whatever is the latest (or used) SDL2 version.

@geennaam

Thanks, I will try to implement this W/A. Do you know any SDL2 software using 8ch mode?

@Raziel

Which binutils version you are using?

@Raziel

Release was identical to RC1.

Now there is a new release with replaced libraries: https://github.com/AmigaPorts/SDL/rele ... v2.30.1-release2-amigaos4

@Maijestro

If you have the SDK installed, "readelf -d binary_name" can show the required shared objects.

Some older MilkyTracker used libSDL2.so, also my Super Methane Bros and ioQuake3 ports do. RebelSDL uses also the shared object.

However, the old ports are often linked to libSDL2-2.0.so. Library should be compatible so it's possible to make a link from libSDL2-2.0.so to the latest libSDL2-2.30.so.

But now when we started to discuss this, I can see that I have made a mistake and library name is libSDL2-2.31.so when it should be libSDL2-2.30.so. I will start fixing this.

@Raziel

Thanks for testing :)

SDL 2.30.1 RC1 is available:

https://github.com/AmigaPorts/SDL/releases/tag/v2.30.1-rc1-amigaos4

@smarkusg

So with SB128 RecordTest actually works because it prints sample data to STDOUT.

@trixie

Thanks for confirming AHI issue. I don't know if there is anyone who could investigate, especially if it's a driver side bug.

There was another AHI issue about playback noise in 8ch mode.

If you had some problems with recording, please could you try this example and check whether it can get past "Before DoIO" log. Thanks.

@smarkusg

I don't know, please test it ("works for me"). I fixed something but then there is some other driver (guess) issue, DoIO gets stuck, also with Martin Blom's test program. If you use HD Audio driver, you need to choose 16-bit recording.

Thanks for the support. Please consider supporting a charity of your choice.
