Good morning everyone, I'm asking you more experienced people if you have a solution to my problem.

I used to program my MSX in the late 1980s, both in Basic and Assembler. I wasn't professionally skilled, but I still enjoyed experimenting. Today, I'd like to start doing something again, having discovered all that material (software and books) online that was very difficult to obtain in my day, even financially.

My system consists of an MSX VG-8020 computer and a 360 Kbyte floppy disk drive, as well as a CRT monitor. I tried downloading some programs from the Internet and saving them to the floppy disk using an old PC with Windows XP and a floppy disk drive that formats disks of 720 Kbytes or more. I know about the issue of the second window on the disk that needs to be closed. I've noticed that if I format the floppy disk from my MSX, the Windows PC reads it and I can save files; however, once the floppy disk is inserted into the MSX drive, it is very likely that it will no longer be read (I have read something, but often the system crashes), and even if I put the disk back into the PC's drive, it will no longer be read. In short, I don't know what to do; perhaps someone of you is more "savvy" with these things and can give me some information. I would like to know how to handle .dsk and .cas files, although I have read a few things online.

I have another question to ask, if I may: ever since I got this computer, I've always noticed, when using the TV, an unpleasant flickering when using certain colors, usually very bright ones. I also notice this flickering on the CRT monitor connected to the monitor output. Should I make some adjustments to the dedicated electronics?

In short, I need to be able to get back to programming in Assembler with a good program, in addition to the native Basic, for the pure pleasure of doing it and to learn more about this machine. If you can provide me with a link to download such a freeware program, I'd appreciate it (perhaps Zen Assembler?), assuming I can then save it to the floppy disk. My dedicated Philips cassette recorder is unusable, and I've tried using other cassette decks borrowed from friends, with mini-jack audio outputs, without being able to load any programs onto my old cassettes.

Thanks for your attention, let's have fun with our MSX!
