Re: ASM6809 conditional compiling
Hi Pere, Could you make use of the following batch commands to create a file called 'files.inc' that can be included in the main assembly? echo ; files to include > files.inc for %%f in (*.PTM) do echo include.bin "%%f" >> files.inc asm6809 ... Note the extra spaces between 'echo' and 'include.bin' ...

Re: French Dragons and the PN41503 motherboard
Hi Stew! It's been a while, you keeping well? Hi Tony, I'm good thanks, apart from the day job sucking the life out of me. Starting to regret not working harder in my youth :lol: Hope you're keeping well too. I really admire what you're doing on Twitter btw. Edit: Double post. That's a new one!

The start, end and exec addresses for a simple binary file can be found with a few PEEKs after loading: CLOADM ST=PEEK(&H1E7)*256+PEEK(&H1E8) EN=PEEK(&H7E)*256+PEEK(&H7F)-1 EX=PEEK(&H1E5)*256+PEEK(&H1E6) CSAVEM"NAME",ST,EN,EX This won't work with custom formats such as autorun programs, but should b...

Re: French Dragons and the PN41503 motherboard
Hi Tony! I don't know if you've already found it but there was a discussion here on the SECAM boards a while back: https://archive.worldofdragon.org/phpBB3/viewtopic.php?f=9&t=10921 It looks like the boards need to be paired as the power connector seems to have a different layout.

Re: Dragon keyboard conversion to USB HID
I don't really know how your setup works, but producing @ on a PC keyboard usually involving pressing shift, which may interfere with the logic at the Dragon end. Also is it coincidence that @ vs " is one of the differences between US & UK keyboards? What happens if you type into a text editor inste...

Re: XRoar video debug builds

OLL '22 Video Games Convention
We had a family afternoon out at the recent OLL '22 Video Games Convention as it was close to where we live. The Centre for Computing History had quite a large presence and I was pleasantly surprised to see a D32 set up with Chuckie Egg. Of course I felt obliged to put my name on the high score tabl...
