So x-user-defined is a JavaScript character type? (I googled as such a command isn't Java)

I'm unclear as to the exact problem since ago can read byte by byte. Is it the file structure you're having issues with or a type of encoding?

normal ascii is in this range 0 hex to 7F hex, so its return 1:1 else if it is bigger then you should return 0xF780 + byte − 0x80.

(Extended ASCII comprises 256 code points in the range 0 hex to FF hex = 0 to 255)

useful for you is at first CreateMemblockFromFile then interpret his bytes with GetMemblockByte

Quote: "15.5.1 x-user-defined decoder

x-user-defined's decoder's handler, given a stream and byte, runs these steps:

1. If byte is end-of-stream, return finished.

2. If byte is an ASCII byte, return a code point whose value is byte.

3. Return a code point whose value is 0xF780 + byte − 0x80.

15.5.2 x-user-defined encoder

x-user-defined's encoder's handler, given a stream and code point, runs these steps:

1. If code point is end-of-stream, return finished.

2. If code point is an ASCII code point, return a byte whose value is code point.

3. If code point is in the range U+F780 to U+F7FF, inclusive, return a byte whose value is code point − 0xF780 + 0x80.

4. Return error with code point. "

Thanks markus it where pretty simple when reading your comment
Iam going to check it later today

I tested both yesterday but throwed a bunch of errors to me ?

I could have written it wrong ???

phaelax..
It where a bit explaining a good way to read a byte file and use the encoding in agk
I have bin away from coding for a long while

Hmmmm
Wonder if they do this in java to read byte files because they dont have read byte or something ???

The command do simply keep read results around 0-256 right??

Kudos for all pointers
Thanks markus for the tip about memory block

I found the stinking error and its fully working now

It where the stinking opcodes
One silly value in a opcode that where wrong

Yes they do
it where one silly value in one single place that made it all fail
Joy off coding

Iam currently cleaning it all up but as you have bin such an helping hand so could i upload it earlier if you want

I spent 1 whole day to correct another error i caused my self while cleaning it up
But its also fixed now

I also found why some games only displayed the intro screen.

In agk do i nead to add a extra key check inside a opcode that is infinit if there is no key press check there also .
Took a while to figure it out
python and java tutorials did not use that as they had some kind of listener plugin ?
It where pretty painfull to convert something like this from all various sources as i where forced to a bit of scrappboking coding with parts from many tutorials


So i have to say that its fully working now

Iam working on adding hex input also for chip 8 demos and games.

They are easier to find as they are usually collected in simple text files.
something like this..

this opcode_FX0A with key wait looks special with this while wend.
maybe the programm counter did not step 2 until a key was pressed.

for this hex input i would add a textbox to file converter and then load it as normal rom.

btw, i wonder why u used val()
do

print(val("0xFFF",16))
print( 0xFFF)

print(val("0x00E0",16))
print(0x00E0)

sync()

loop

In the java/python code so does it seam the key input listener is outside and regsters input even if the code is in a loop
Kevin picone already told me that the compiler reads hex as numbers
I thought i had to convert them to numbers with val in agk.
The bug where not there but i had to do a few hacks to get it to work n agk
off to party today so i might work again on the code tomorrow and release the latest?
I do not do to much programming lately

I dont get to much feedback so i dont even know if the emulator is popular enought to continou to work on ??
I always wanted to do a emulator and is why i tryed to do a simple one before i try more advanced
Have my sights on msx / spectrum in agk
or even c64 in the end.

I'd never heard of it until seeing your post.. so i'd assume the majority of people here don't really understand what it is.

unforunately c64's emulations need to be cycle accurate, as the software written for it tend make heavy use of raster interupts. Getting old stuff to work would be easier (some old emulation cache scan lines to make faster), but there mine field of timing problems when interleaving the cpu/graphics chips together.

myself started a c64 emu in blitzmax but i can't get it to work because some opcodes, i guess.
you can continue if you want.

yes sure markus
I could take a look
Post the blitz source here so will i try to check it later on

i think you are right kevin
Most tend to look at n64,ds and later machines then the early ones to emulate.
I never thought i could put together a chip8 emulation in agk
