don't worry about that, Ciaran. Seeing A, B, E F is good enogh as I am sure they are updated when the program loads the 16 bit registers. Anyway I will verify that point ... I am sorry I have not been able (no free time :-( ) to make a longer test. I hope I will later tonight I will download your la...

Hello Ciaran, now it works. If I enter set $e=0x43 and then set $f=0x21, both registers are updated on screen, great! But if I do enter set $w=0x9876 then nothing changes on screen, so it seems that the EF pair is interpreted *only* as individual registers, but not as a double register, as AB is con...

I've had a look and this turns out to be a fault in my GDB patch - none of the 6309 registers were flagged as 8-bit, so the results were misaligned. Now, can I remember how to build the Windows binaries of GDB? :) Edit: and the answer is "maybe". ISTR the way the binary is built affected how well i...

Hello Ciaran, I have downloaded the file "m6809-gdb.exe" from "index of /temp/xroar", and the last XRoar snapshot (110), I hope this is all I'd need I will test it this afternoon. I need to make a long trace/debug session on my music engine conversion from MSX-AGD code. I will let you know how it go...

Hi Ciaran, I am really very busy with my V9958 project, but have installed you last version and keep using it with GDB to debug and I have not find any issues by now. I can execute games / rom files from command line using bat files as I had been doing before. If it were possible, I would really app...

Hello, time to talk about the latest news about the AGD engine conversion for the CoCo/Dragon with V9958 and YM2149 chips This is just another (bad played) video to show the new part of the AGD engine that I have just converted. It is the part that deals with the effects/sounds instead of the 'old' ...

Hi John
Great job, congrats!
Can't wait to test one of these modules using both video and sound!
cheers

That is just awesome! Both on the technical side and on the walkthrough. Thanks a lot for the great work! Thanks for your kind words, Robert In fact this has been a very exciting way to learn about that nice and unknown to me video chip. But the AGD engine is not yet fully converted, there are thre...

Hello, the AGD engine conversion for the V9958 video chip using the HD6309 PCU is just finished For anyone that would like to have a peek at the result, I made a video, in fact a whole walkthrough despite my low gamer skills :-( This is the link to the youtube video ... cheers pere https://youtu.be/...

Hello John,
you pack with the oojamaflip has just arrived safely, thanks a lot!

Not in a hurry to build it immediately, because I am using
mini-MPI from Ed Snider or a standard Tandy multi-Pack when
I do need more than two cartridges ...

cheers
