Re: Oric emulator in Python

Sounds very interesting. Moreover, you had already worked on an emulation of the graphic chip. so it could be a good start. What I am especially interested in is the possibility of automating some non regression test. Recreating an Oricutrom looks ambitious. But we can have some exclusive features ...

Oric emulator in Python

I think it could be interesting for us to create an Oric emulator in Python language. To do that it will be possible to base this project to the 'py65emu' library. And I think this work will be not very difficult with help of different python libraries. In the first time it will be just neccesary to...

Re: looking for a pixel flood fill routine

Thank you for yours help.

I think i am going to loot in anciens Oric archives to find an assembly code of the floodfill algo.

The Lorigraph floodfill Algo look like very speed and optimal but it's difficult to disassemble it for me.

Re: is the Oric rom open source ?

BTW, how they manged to support C64, MSX, Apple][ which ROMs are not open source too? Thank you i will communic...

is the Oric rom open source ?

Hi, I asked the 8bitworkshop website if they could add the oric in the online emulators.. He asks me : if the oric rom is open source. .....? https://8bitworkshop.com/v3.8.0/?repo=sehugg%2Fmminer-apple2&platform=apple2&file=mminer.s It should be possible, if there is an open-source BIOS available.

Re: looking for a pixel flood fill routine

This is an interesting subject. I'm a noob regarding the subject but I wonder: do fill algorithms on Oric take advantage of what I would call "byte structure" of the Hires screen? I mean, if a byte equals $64, it can be completely filled without checking neighborhood (might not be as simple as that...

If wonder if this would work:

Code: Select all

120 IF T<>1 THEN ELSE IF TY<26 THEN TY=TY+1 ELSE T=0:PLOT TX,TY,32
Thanks Dbug but unfortunately

Code: Select all

PLOT TX,TY,32
is still displaying when

Code: Select all

T=1
and

Code: Select all

TY=25

Re: [MOCAP on ORIC] This useless TAP file is funny

Wonderfull ! Gratz JB !

This 3D make me dreams of many possible 3d games. Cars races, flight simulator, submarine,

I think that open a new univers of game development !

It will be nice to have a little documentation with samples in C to draw 3d objects with Gloric or lib3D. :D
