Doesn’t BASIC continue after the SYS command where it left off when returning from the machine language code?

Couldn’t it be that the 128 won’t keep up with the RS232 stream if interrupted by disk accesses? The kernal load routines are sometimes stalling when waiting for sectors to be read in the drive. Are you using some kind of handshake to ensure both sides are keeping up?

Yes I think so. This appeared on the C64 in C64C and that had the new chip.

I heard that some eprom programmers can be put directly in the EPROM socket to simulate RAM as EPROM. That’s probably the easiest but maybe most expensive solution.

I made a custom solution where I have a userport transfer program in the internal function ROM to boot it quickly on reset and then a Raspberry Pi connected to it to get network connectivity. It makes it possible to send programs to and from memory and disks. However, I have no solution to test ROM images for cartridges. This could be a way to do that perhaps.

A C64 fast loader should work as-is if you prepare the bank in advance and not enable 2 MHz. I'm also annoyed by the requirement to turn off drives to use a fast loader, but it isn't strictly necessary. You need to find one that can be forced into using a 2-bit protocol without tampering with the ATN line.

BackBit seems to be getting some C128 support. It's getting a native file browser.
It doesn't handle 2 MHz and I'm not sure if it can boot C128 programs. I'm hoping it does.

Ah, I see. I was confused because I assumed that the question was aiming at not loading the file contents.

The idea is simple and you're only checking the last track and sector. I still don’t understand your reasoning. How would you find the last track and sector without traversing the linked list of sectors that the file consists of?
