Atari 8-bit emulation (BASIC and lowercase/inverted text)

[largactyl]

Hi all,

 

I'm using Altirra 2.10 to emulate an Atari 800 (or 800XL, or 1200XL, issue is the same).

I am booting Atari DOS 2.5 with the BASIC Rev. C cartridge attached, and a host device (H:) to save files. This works fine except for two things:

 

1. Cannot enter lowercase text at all

2. Cannot enter inverted (high-ATASCII) text at all

 

Yes, I'm kind of a n00b to Atari 8-bit emulation, and would like to try out some BASIC programs which use lowercase and invented chars in PRINT statements.

 

Altirra's helpfile claims that Caps-Lock and End should enable lowercase and inverted text respectively, but it simply does not work. So I'm starting to believe there's something obvious that I'm missing due to my lack of Atari knowledge.

Any ideas?

Update to 2.40 and try again -- 2.10 is a year and a half old:

The issue is that you're using the internal fallback OS, which in 2.10 was pretty incomplete. If you plug in the Atari OS in System > Firmware > ROM Images, it'll work. You might as well update to 2.40 anyway, though, which has a lot of bug fixes and improvements.

For now I've hackishly "solved" my issue by hex-editing the .BAS file in my host device folder. Appreciate the advice though, I'll give that a shot next time... I've upgraded to 2.40 and already seeing improvements (PRINT statements in certain graphics modes seem to behave more as intended, for one).

 

And thank you for an excellent and very well-rounded emulator!
