Emulator r38 Released

[Johan Kårlin]

Every release feels like christmas. THANKS Michael Steil and everyone that have contributed! And a special thanks to @StephenHorn for the improvements to VERA! I have really been waiting for raster line and sprite collision interrupts!

Great also that WAI is now implemented. I actually thought it worked already. I have been using it for quite a long time but the code must just have resulted in a busy wait...  This must be the answer to why WAI (sorry, trying to be funny) has been so slow in response.

Can someone tell me what Chars are that on a DE Keyboard layout?

 

Ctrl + = and Ctrl + + will toggle warp mode.

 

I have no clue how to enable warp mode or how to identify I am in warp mode. Any idea?

Try ß, +, -, = ... those keys near the backspace key... If you're okay with warp mode being enabled for the whole session, you can specify -warp on the command line.

If it really doesn't work on non-US/ISO keyboards, I can change the shortcut to something else in the next release. In this case, file an issue on GitHub against x16-emulator.

Hmm ... according to this picture the US keyboard has the + and = at the same key ... just shifted.

On a German keyboard this is the "´" key and the "`" key. The later one is with SHIFT. The documentation should better read CTRL-= and CTRL-SHIFT-=

It works ... however the same key is in X16 the "UP ARROW" key.

Great progress!

The following C code example works with cc65 for writing/reading files with an sdcard image attached to the emulator.  If the load/vload worked as well I could add a logging capability to libX16 that would let a program do debug logging to a file for debug purposes.  I'd love to support something like that for the host filesystem interface as well someday.

I tried r38 on my Mac and it doesn't go. R37 works fine but when I try r38, I get this. Any ideas?

Scott,

It should work.  I installed r38 on my  Macbook Air and it runs just fine.

 

[StephenHorn]

I'm not a Mac guy, but is it possible Scott is missing something like C development libraries or something? Could/should they try installing GCC or something?

[SlithyMatt]

The answer to "should I install gcc?" is always YES

[SerErris]

SDL libraries ??
