ty :P not that good i don't think lol, i'm sure you guys could come up with better, mine are a little buggy and poorly made in the grand scheme of things ;p but its nice to have some games on the system ;p I think you should do some, possibly do a chip16 version of your pascal game you did ;p

Did you mean this game?

Not sure I could do that...would be too hard I think LOL
I do have one idea for a game though if I get time and figure it out

@tronix: with your image converter program, any change of allowing the user to specify a RGB transparent colour? This would be most useful!

For example: all 255,0,255 pixels become colour 0 (transparent) in the final .bin image file...

Oh, and an enlarged version of the converted image would be great as it is very very hard to see how the colours have turned out if it is small, like a 16x16 pixel sprite...especially on a 30" monitor that I have here on this machine

Also specifying a custom palette would be very useful!

I am seeing if I can make something simple to convert a bitmap to chip16 format with custom palette + transparent colour (and zoom)

paul_nicholls · August 2nd, 2012, 01:22

Ok, here is my version of an image converter for Chip16:

I have attached a zip file with the .exe file.

You can customise the palette + load & save palettes to .pal files (raw RGB palette format), and scale the images.

Also can specify a transparent colour too!
Enjoy!
cheers,
Paul

Bump...anyone home?

tykel · August 7th, 2012, 07:59

Yes! I tried your image converter and it works great!

Suggestion: maybe make it so the transparent colour selection works on one of the palette entries and not an RGB colour directly?

What if I allowed you to pick a colour from the source BMP as the transparent colour using the mouse as well as manual entry?

Hi guys,
I think we need adding to the specification new opcode - reminder of division (module).

Code:

MOD Rx,Ry

because my software emulation (procedure) may take 255*3 cycles (when ry = 255) and it's very slow.

Code:

mod:
; input:
;   ra = fist number
;   rb = second number
; output:
;   ra = result
      mov   rc,ra
      sub   ra,rb
      jnc   mod
      mov   ra,rc
      ret

I am using MOD in all my demos: sinedots, sineflag and twister.

Yes, that should definitely be in. Next revision should have that.

This should be good for the spec

Code:

A3 YX 00 00	MOD RX, RY		Divide value of register Y with value of register X. Remainder is stored in register X. Affects [z,n]

(removed carry from affected flags as i dont suspect we will have overflow on a remainder).

Possibly have this also

Code:

A4 0X LL HH	MODI RX, HHLL		Divide immediate value HHLL with value of register X. Remainder is stored in register X. Affects [z,n]

Yes, and also have:
MOD RX, RY, RZ for complete spec. -)

Indeed! I did ponder it! Didn't want DIV to feel like it wasn't so important as the rest of its friends xD

There is one other addition to the spec that I really would love to have - read/write byte (8-Bit) from/to memory...not just 16-bit words.

There are a lot of times I need this but it isn't in the spec yet

I don't think so. shl/shr/and/or operation is enought for change bytes (8bits) in memory.

That maybe, but the code then becomes slower, larger, and more complex than just being able to store/read a byte directly...

8bit read/writes arent uncommon for higher machines. Even the PS2 has 8bit memory read/writes :P It's also not like we have too many store/load functions already.
