Floppy images (.img) have the same problem. Just tested.

Which proper size ? The sizes of the floppy disk images are different.
Are you able to load any floppy disk image ?
If yes, which format and size ?

Expected size is HEADS * TRACKS * SECTORS * SECTORSIZE
And for basic images you have that defined.

static LEGACY_FLOPPY_OPTIONS_START(bbc)
LEGACY_FLOPPY_OPTION(bbc, "ssd,bbc,img", "BBC disk image", basicdsk_identify_default, basicdsk_construct_default, NULL,
HEADS([1])
TRACKS([80])
SECTORS([10])
SECTOR_LENGTH([256])
FIRST_SECTOR_ID([0]))
LEGACY_FLOPPY_OPTIONS_END

this means 1 * 80 * 10 * 256 = 204800 is expected size of file

Unfortunately, I doesn´t have any floppy disk images with this size.

It seems, only 8K/16K cartridges are working.

Well no, I can make disk check more flexible to allow such things.

In principle the size of 204.800 bytes seems to be correct.
Can load the floppy disk image (Elite).
The game is for the BBC Master and not for the BBC Micro.

bbcbp128 driver
The startsceen is ok but later it switch to another graphic mode (no more useful for the BBC Micro) which is supported by the bbcm driver (BBC Master).
