Re: fossimon - an NMI based monitor for divMMC and esxDOS
That's excellent. It works! Is this address ($66) fixed or is likely to change with subsequent releases of fossimon? If it's fixed, I could add a fmon pseudo instruction to the 48kb version of Specasm which would take you directly into the monitor when executed. The Next version of Specasm has an n...

Re: fossimon - an NMI based monitor for divMMC and esxDOS
I had a quick play with fossimon this evening on my OMNI HQ. The OMNI is running EXSDOS 0.87, a version older than what is recommended by the documentation, but it does seem to work, and it's great! Thanks so much for this. Is it possible to programmatically enter the monitor using one or more asse...

Re: fossimon - an NMI based monitor for divMMC and esxDOS
A welcome tool, @bob_fossil. Very nice. I appreciate that it has customisation features right from the get-go, along with the ability to save any custom settings with the “cfg *” command, so they become the default on the next activation. Key repeat is currently a bit keen for my liking. It’s seems...

Re: Question... 2nd joystick button?
Just to eliminate the obvious, many emulators can assign joystick / controller buttons to whatever keys you choose. With real hardware, the question is "Which joystick adapters did support more than just four directions and fire ?" On my +2, the divMMC Future's Kempston joystick interface...

Re: Rockfall: why does this game crash in 128 mode?
P.S. I have found another issue with this 128 fix — though it doesn't matter for the purposes of my modded version, because I won't be using the demo playback routine. The title screen calls a routine at 60458, which waits for a keypress, and if no key is pressed, eventually goes into "attract...

Re: R-type question
esxDOS v0.8.9 supports loading .scl files directly so you don't need to do this. You can open them straight from the standard esxDOS NMI browser or my replacement long filename browser.flatduckrecords wrote: ↑Mon Feb 05, 2024 7:53 pm If your DivMMC's version of esxDOS is up to date you should have Nihirash's dot-command called SCL2TRD, e.g.

Re: Trap Door 128k mod
Loads on a real Spectrum using a divMMC and esxDOS. Unfortunately, it looks like the IM2 table that does the AY sound track is in uncontended memory as there is constant 'snow' on screen in the title menu and in game.

Re: Rockfall: why does this game crash in 128 mode?
I've re-uploaded a version which no longer crashes when you lose a life. When you lose a life the code sets the stack pointer to a value held in $5b88. On 48k machines this address is inside the printer buffer area at $5b00 which is a safe area to store your own data and code. 128 BASIC however uses...

This should work when loaded from 128k now. The original loader was one large CODE block loaded from 16384 which stomped over the printer buffer which 128 BASIC uses for paging. I've also applied my patch for the sound effects.

Are you directly calling the ROM tape load functions? When an esxDOS dot command is executed the normal ROM is paged out as the dot command is loaded into address 0x2000 / 8192.
