Limit on size of GRAPHICS.DAT?

Is there a limit on the size of the GRAPHICS.DAT?

I can load my current file which has swelled to 514KB. However, if I replace a graphic so that it goes to 525KB, CSBWin crashes when I click on the 'Dungeon' button.

Are there any checks in the original code that could be removed. Perhaps it's more complicated than that....?

Hope it's fixable, I still have a long way to go before all my new gfx are imported...

Additionally, on the 514KB file, once I click on the 'Enter' button, the doors open and I then get a Windows messagebox saying System Error 44 and the game exits.

I am thinking maybe the limit is 512KB?

EDIT: Tested a file of 510KB and it was fine, no errors, game plays normally.

Ship the thing to me and I will try to figure it out.

I used to get the system 44 error after I had accidently resized a graphic. Have you managed to resize any of the separate graphics from DMout, and make them larger, and if so, how?

Oh yes, most of them are resized -- but that's not a problem if you hex edit 0558.dat to reflect the new sizes. This is a massively customised file that has all kinds of new sized images in it. No, the problem I believe is the overall FILE size of the .dat.

Mr. Stevens, I am sending you some sample GRAPHICS.DATS of differing sizes as I type this.

Incidentally, the file I am changing is the End Game Scroll -- by saving it out from Photoshop with different amounts of dithering, I can easily generate GRAPHICS.DATS of differing sizes. It's the file dmout0005.bmp as generated by Rain's DMEXTRACT program.

I am wondering if perhaps there is an upper limit on the amount of memory any SINGLE graphic takes? Hmmmm... maybe I could get the GRAPHICS.DAT bigger by adding lots of smaller images and see if that also causes the problem...

Try CSBwin9.8v22.

There were really two problems. Graphic number 5 was bigger than
32767 and the total sizes of <something> was too big. I doubled the
size of memory allocated (from 1 meg to 2) and 'un-signed' the graphic
sizes. I do not understand the memory allocation and things might break
again. It may come to pass that I will need to study it a bit.
