Re: at67 emulator

I haven't had a chance to build/run it under OSX yet unfortunately. By default the emulator will try and run in fullscreen mode, try putting it in windowed mode and see what happens. Create a file named "graphics_config.ini" and save it with the following contents into the same directory as the exec...

Re: at67 emulator

I’m not a C++ programmer, but it would be helpful to know why I needed to carry out the above steps? I have no idea, we would have to look at the project settings that cmake produced for VS on your system. If I were to guess, I would say that /SUBSYTEM:CONSOLE was being forced in your build somewhe...

Re: at67 emulator

There're some quirks. It's reaching 96% speed if I interpret the indicator correctly, but 36 fps? It defaults to a non-standard 64K and the the startup sound is choppy (probably due to the speed). I haven't figured out much the controls. F11 switches between controlling the Gigatron and the hex edi...

Re: at67 emulator

Hi, I have made some progress on at67 emulator and now have it compiling under windows. My next problem to solve is the message ‘CPU stall...’ keeps being echoed to the screen, has anyone else seen this? You had this problem because you built the code in /SUBSYTEM:CONSOLE mode instead of /SUBSYTEM:...

Re: at67 emulator

Thanks MCD for compiling it. This might be more a question for at76. It looks like the emulator emulates PS2 keyboard entry, but does it also work with the save/CTRL-F3 mechanism to save BASIC programs? I tried and while save seems to have done something, when I tried CTRL-F3, it didn't look like i...

Re: at67 emulator

Some of the stuff I have read in here has made me grimace, it's trivial to build my code-base under both Windows and Linux, I have done it dozens of times on old boxes, new boxes, fresh installs and VM's. This seems blindingly obvious to me, but never ever ever download unknown code, shared librarie...

Re: Going back to early 1975

That is pretty cool, if you get a chance could you post a CRO screenshot of some zoomed in signals, original TTL vs HCT; would be great to see a comparison.

If you do find the time, maybe show some short and long PCB trace signals as well.

Re: Which sprite/memory functions to add to ROM?

SYS_SpriteRow_118: Does 4x4 block copy? SYS_SpriteCopy_118: What’s the difference? Same? SYS_ClearRow32_56: Looks useful. I can add this.. SYS_BlinkyBlast_142: Doesn’t sound too generic... But it is cool.. I'll sleep on it SYS_DrawPixel2x2_32: Small but usefull SYS_SpriteRow_118: SYS_SpriteCopy_118...
