Thanks to Al uploading Vyper and a few other goodies, have tested Vyper under...almost latest git.



-Thom

I did a test:

set sp to 0x10
set pc to 0x0 which contains 'push sp'

Do a single step:

0x10 is written to DATA RAM:0x11

So it seems to increment the Address, and write the initial SP value to that location.

Thanks for the explanation!

For the first one, it's common for Z80 systems to not decode the top 8 address bits on I/O accesses, so they're just resetting the same device 4 times in a row.

Yeah, we've been having fun emulating serial at the wire level, with real clocks and stuff. So we're emulating all the annoyances that come with it :-)

Not everything is converted yet, but one day, one day...

Checksum is actually a simple additive, not a CRC -- will submit this change soon. Tested both of your images, DOS is OK and CP/M (cpm11victor-kryoflux.7z) has minor problems:

I'm working on MFI writer and A2R reader for samdisk - not submitted yet. SCP to MFI conversion (and A2R to DO, for unprotected disks) does seem to work.

MAME 0.211

As we pass the half-way point of 2019, it’s time for MAME 0.211, with all the excitement that brings. In this release, SGI Indy and MIPS RC2030 workstations have been promoted to working. This is a major milestone in RISC workstation emulation. If you’re feeling nostalgic, why not try one of them out, and install IRIX or RISC/os, respectively? This release also includes better support for the China Education Computer Apple II derivatives, along with a preliminary software list. This opens a window to Chinese classroom technology in the late ’80s and early ’90s. Speaking of software lists, we’ve added over five hundred cleanly cracked Apple II software titles, and imported a whole lot of ZX Spectrum cassette images.

Looking away from computer emulation for a moment, Game & Watch preservation keeps progressing, with the addition of Ball (the earliest Game & Watch release) and the panorama screen version of Donkey Kong Jr. The Gaelco/Salter Pro Cycle Tele Cardioline exercise system has been promoted to working, and the Pro Stepper system has been added. System 573 MP3 audio has been greatly improved in this release, and support has been added for more Bally pinball sound boards. ClawGrip added example programs from the V.R. Technologies VT03 software development kit. Gemcrush, a rare brick breaking arcade game, has been added in this release.

There are lots of other improvements, including a fix for the fatal error when switching away from MAME in Direct3D full-screen mode. You can get the source and Windows binary packages from the download page.

That was what I was implying with set_romslots in my post above. I need to use this reference in device_add_mconfig though, and don't think this is possible, is it?

If I end up using an array of bbc_romslot_device in the machine and the slot device then it will get overly complicated as the machine should see them as a single array, so would need to always check whether the slot device implements a particular bbc_romslot_device before falling back on the machine bbc_romslot_device. This would also confuse users as the order of slots would be incorrect, ie. from commandline -rom1 would refer to slot12 and -rom5 would be slot0.

In more familiar terms, say you have a machine with:

and in a slot device I want to change the default rs232_device with:

This is exactly the type of change I'm trying to do with my bbc_romslot_device.

Maybe a better alternative is to move the 4 default romslots to the slot device, so that all bbc_romslot_device config is handled in the slot device without having to manipulate anything that may have been configured in the machine. I did this for the default 8271 in my bbc_fdc_slot_device so should be easy to implement.
