Does Tiki100 still work?

[stefano]

I left the TIKI-100 behind for a while, observing other people successfully developing test programs and games for it, but I must be missing something.
Could anybody confirm the current TIKI-100 target is able to produce high resolution graphics and/or target specific console output? What is the right build process?

The himem graphics location seems to not be working - it's sorted now.

Thank you.

I'm cautiously checking and improving the graphics sections, the changes are sometimes multiple small progressions, but it looks it is effective enough.

Please have a look at mono sprites, in screen modes 2 and 3 the x coordinates are squished:

For comparison, it should look like this (Z1013 KRT):

In addition, mode 2 has red vertical "jail bars" across the screen.

Mode 1 is fine.

For testing, grtest_tiki100.zip is on my Google Drive:

P.S. games.h support would always be a welcome addition to any target.

games.h is now built also in the TIKI100 library

I unsuccesfully tried to import the bit banging code by Enjo for the MC-1000, but while I was playing with the sound stuff I was incredibly lucky and stumbled into this page:
https://map.grauw.nl/articles/psg_sample.php

I got a working playzb4() implementation by picking and mixing code found there and elsewhere on GitHub.
It worked almost immediately, I'm sure it is not well optimized but the sound quality is rather good compared to the bit-banging versions.

You can try it with examples/sound/bit4.c

Can you please take a look at this issue?

P.S. Virtual Joystick support is working fine, thank you Stefano.

I've delegated the sprite routine for non-mode 1 to the plotpixel variant so it should now not be squished in the lower resolution modes (though a bit slower).

[RobertK]

Excellent, thanks. The sprite speed is still ok compared to other targets.
I have now published a new Deepspace release which adds versions for the Tiki-100 and the TIM-011, both are very useful target systems.
