Re: Raspberry Pi baremetal port?

Linux has a very bad level of performance with anything that needs a fast response. That means it's a poor choice for MIDI. Even if your thread goes real-time, I'm pretty sure Linux still preempts your thread for up to 5ms every second. Not good enough. Uuh. You are comparing apples to oranges. The...

Re: Raspberry Pi baremetal port?

What makes the baremetal SDL better than just installing the various libraries on top of Stetch light and then compiling Hatari? I use that now and it works great. ?? If done right, a lot less overhead and more or less instant boot. No need for a full-blown Linux kernel on a machine that is suppose...

Re: Atari TT + NetUSBee Lite: Not working: Writes not happening. Any ideas?

Besides the added fuse (that could be dead on some TTs, so check this first), there are more differences from ST to TT on the cartridge port. Most notable, it has a different timing (16 MHz vs. 8 MHz) and some signals (that are 68000 specific) are generated by additional logic since they are not ava...

Re: ROM port Ethernet adapter

GEM=ROM Your main problem is that with GEM=ROM, the ROM AES (that is not designed for preemptive multitasking) will run solely in supervisor mode and since MiNT doesn't do task switching in supervisor mode, you basically degraded MiNT into a single user OS with the AES and Desktop eating up all the...

Re: ATARI ST Core

As I said in some other thread, I am willing to port the ST core. But being obsessive about cycle accuracy, I don't want to just port it without implementing major improvements in this aspect. So I need to find the time for that. I need to finish a couple of "real life" projects and I mig...

You can write an assembler in Basic, and once you have that, you can use this and write it again in assembler. That's how it has been done in the past.

If I remember right, the card/code is supposed to sense the port where a monitor is connected at boot time itself. Maybe your converter doesn't forward signals correctly?
