ok...again my experience... Pete & Co can correct me... but

to mimic c64 sprites (so to say when using a c64 "back engine" while putting soft sprites on top) our speed advantage of 1,77 Mhz gross vs 0,9 Mhz is not enough... and for "quick" conversion like Bomb Jack you need a 6502 engine backend...where you adapt or put "sprite routines" on top...

but the structure is different... screen layout will vary to c64, ram usage is higher due to prerendered sprite data but c64 can have 60k while we can have 56k... and and and... oh... and it should run in 50/60 fps...

My skills are not high enough but Kudos to the ones who can...

the xe cart... what an ugly title screen....

you can do that with turbo basic but it will be slow as hell... you would need an assembler routine to do it right incl. font with masks... and you need to restore the background... not so trivial for beginners I have to admit... we do not have several playfield layers like Nintendo Gameboy...

and there is a significant difference between PMs and graphics... in PMs a "0" becomes transparent and the background will shine through (if priorities set right) while in static graphics like in gr.24 you can not make the "0" transparent... transparent to "what"?

question...

you want to load a gr.24 pic... and then you want to print text on it? or do you want to have text fly around?

if you want to display text over the screen (like f.e. "press START to begin") you can do that with the text command of turbo basic... if placed over blank background you won't see it when using the text command. the issue is that the text command will copy the graphics over the graphics that's why you will get the "box" style... so if the character graphics contain "0" then the text command of turbo basic will not "skip" that byte but will put it on screen which results in erasing the gfx.

so little bit more info then we can talk about possible solutions...
