For reference in TOS2.06 UK image the offset for the logo is 3257E and ends at 32985Atarian Computing wrote: ↑Sun Mar 10, 2019 9:03 am The offset where the logo begins in TOS3.06 is 35FF4

Now that you mentioned patched TOS versions, it occurred to me that since this is the ThunderStorm patched 3.06 TOS version (for obvious reasons), the offset might not be the same. Also, mine was the US version which I then changed to UK keyboard layout. So yeah, probably best to disregard my offset figures.thorsten.otto wrote: ↑Tue Dec 31, 2019 4:16 am The offset is not quite right, and also depends on the language of the TOS. For TOS 3.06(us), the logo starts already at $35fe8.
The table below should give the absolute address for all (official) tos versions (subtract $e00000 to get the file offset):
Most patched TOS versions that are floating around (like CZ and PL) are based on the german version.Code: Select all

The routine that displays the logo is located at $e0074a in TOS 3.06, and $e00762 in TOS 2.06 (for all language versions).
As already mentioned above, the logo is 96x86 pixels, thus 1032 bytes of data.
The thunderstorm is only a patched TOS, i doubt that they changed all the addresses (although it would theoretically be possible if they used my source to recompile it). But you should be able to check it by disassembling it, the routine looks likeAtarian Computing wrote: ↑Tue Dec 31, 2019 8:36 am since this is the ThunderStorm patched 3.06 TOS version (for obvious reasons), the offset might not be the same.
