It’s been a while! A quick update to the OSCA emulator is available below. This incorporates a fix for a parity bug in the CPU core for subtract instructions (Thanks to Enzo for reporting this, and Daniel for reminding me about the flag’s dual-purpose!). Also modified is the built-in debug window which didn’t seem to be very useful for setting PC breakpoint etc since the code was refactored to be multi-threaded. This now works better than it did before.<\/p>\n

Also included are a couple of extra (experimental, as ever) features:<\/p>\n

Mouse Support<\/h3>\n

The emulator will try to support a Microsoft IntelliMouse (3-button with wheel). Activating the mouse driver in FLOS should kick this off. In addition, you can use the BREAK<\/em> key to toggle locking the mouse within the emulator window, although this feature is very basic.<\/p>\n

RS232 Simulated Uploads<\/h3>\n

To make life simpler for uploading\/downloading files the emulator will mimic Phil’s Serial program internally. So you can send a file from the emulator OSCA machine and it will be stored to an\u00a0incoming<\/em> directory in the same folder as the emulator binary. Alternatively, you can set the emulated machine to receive (FILERX or RX) and use the RS232->Send File menu command to transmit a file into the emulated machine. Hopefully this makes for simpler debugging.<\/p>\n

There still seem to be some speed stability issues, so when I get some time I’ll try to take a look at this more closely. For the time being, therefore, you may want to use a previous version if that works better for you.<\/p>\n

In the meantime, happy emulating, folks!<\/p>\n
