Scandy: I have no idea what you're trying to achieve but look at MPU code in Allegro linked into MBF: static void mpu_output(unsigned char data) { int timeout; if (wait_for_mpu(0x40, _mpu_port+1)) if (_sb_irq>0) // If timed out: Digital section active? { _enable_irq(_sb_irq); // GB 2017, to prevent …

Your however using /dev/sdb, which to me means it is not a real floppy drive. But probably a USB Floppy Drive, which uses a completely different protocol called UFI. You are right. It's acttualy TEAC. FDC controller is embedded inside and system has no access to low-level floppy functions. That's …

It's not the same. Block devices have stricter requirements regarding read/write sizes and offsets, may require explicit seeks... there's no guarantee the C library will take care of that correctly if you use the buffered I/O functions (which DOSBox does). Hmm. There should be warning in DOSBox …

So short answer: No, no equivalent for direct manipulation with device. Why it is problem? Work with block device is just as work with regular file. Seeking, reading, writing. It should work. It is safe just to comment checking macro?

What? /dev/sdb is block device. MOUNT is for directories. Am I wrong?

Which is exactly what I want. /dev/sdb is floppy device. I don't want to use system mounting because caching, I want direct mount from Dosbox. dd if=/dev/sdb of=/tmp/image.img works perfectly. IMGMOUNT /dev/sdb - file is not a file but directory. What?

Hello, guys. I am confused: Filename imgmount.png File size 15 KiB Views 571 views I can mount Floppy Image without problem but device is marked as directory. Why? Is this OS bug?

gerwin: Hmm. How was the thing then done in vanilla doom? There is no source code? I can do it through V_DrawPatchDirect() as it is done in I_InitDiskFlash but blitter would be nicer.

Youtube works fine, but if you want high quality you kinda have to feed Youtube a pre-sanitized version of the video. If you want absolute perfect pixel scale you need to turn the 4:3 320x200 VGA into 2880x2160 which is a 9x rescale from the source resolution post DAR. Absolutely no way. I've …
