@santiontanon this calls for a Tales of Popolon 2

I am thinking in msx2 with the right palette those 4x1 textures have amazing potential.

may be that the msx1 does not have the same speed brake than the ti/99 (even if the vdp is the same) one could achieve a little more fps?

yes, it seems the author is facing some challenges due to the 256 bytes memory limit of the TI-99. Probably is easier to do this on an msx.

Very cool for a 16 bit machine impressive. The TI was my first computer and it is a nice machine. I still have one. The CPU is very powerful but the design to the memory is very poor... very impressive...

I had one too: A TI 99 4a. Oh man... I spent some nights with 'Parsec'

the author optimised it a bit, now is quite faster:

Getting that frame rate at full screen is quite impressive! So much potential for this 4x1 pixel mode!

I'd go for an msx2 game in order to exploit faster i/o and two pages

ARTRAG: does this technique on MSX2 offer more potential than the one you did with Wouter?

Screen 4 with 4x1 pixels implies a lower resolution than screen 5 with 2x1
You can get an higher frame rate due to the lower number of columns and even if you cannot count on the VDP commands you can unroll the code for any height of the columns
At cost of few KB of automatically generated code, I think it could go faster than mine in screen 5
