Re: Number of colors

Re: Data writing

This is fixed, with a $ 25 xbios and a compilation order before calling the routine. This bug was in MI-3, and I do not use a palette change in this program . It's quite similar to the pallet change bug in MI-9 When I had the picture by MM41 I understood the problem. He confirmed that now it works w...

Re: Data writing

Before having the image, I thought the bug was producing by writing the file, and I was expecting to see an image with corrupted data.
(I never had this bug with Steem and Hatari)

Re: Data writing

Apparently, the problem does not occur during writing
By the way, I noticed that the mouse also disrupted a routine acting on the palette ($ FFF8240) but only after compilation. But this is solved
It's all the more complicated for me because I have more Atari to do the tests.

Data writing

Is it possible that the writing of data (on diskette, hard disk or Ram disk) is disturbed by a system interruption or another reason ?

Re: MI-3 picture format converter

It's weird because I've never had this bug on Steem v3.2
Can you send me a badly converted BMP image and the corresponding PI1 image.

Re: Gemdos error handling with Steem3.2

Pea (a3) is ok, but with Pea A3 you enter the datas on the address I realized that this version worked even after a crash of the second version that reads the file at the end So I still looked at my mistake. In fact, I replaced the Seek_offset variable in Fread with another, and it was not initializ...

Re: Gemdos error handling with Steem3.2

here is the first test, the palette is not good. After adding low resolution at medium resolution, he tripled the decoding time of medium resolution images. (I may be able to separate them) It is not good to use the file size specified in the BMP header because it is not always correct and can cause...

Re: Gemdos error handling with Steem3.2

After the first -64 error returned by Fseek (Gemdos $42), sometimes Fread (gemdos $3F) returns 0 in D0, but the loaded bytes do not match what is requested. And without reset, nothing good Well, I'm giving up this loading mode which will be slow for this file. Also, I do not know how to use the Fsee...

Gemdos error handling with Steem3.2

Gemdos returned error -64 (file pointer to invalid segment),. Normal because the file size was incorrect in the file header. After correcting this error, why does Fread always send me an error if I do not restart the emulator? (Whatever file I'm trying to read) moveq.l #0,d0 addq.l #6,a3 ; 2(a3) bsr...

Re: MI-3 picture format converter

I'm doing a routine to load 24-bit BMP images (reduced format for now)
And here I understand that I have to read the file at the end to have a correct color palette !
It makes me angry :evil: :evil: :evil:

Well I have never heard about any compression byte. At which offset is it? 0? If so, hardly any software parses this. It can be masked out in case of real problems.
