Also, if I were to just interpret the string as UTF-8, it would also break, because these characters would be interpreted as multi-byte sequences, since their value is > 127 (eg a strlen() for UTF-8 would give different results than a strlen() for codepage 850). This isn't true because strlen() …

So, if you have a >2TB drive, you can't describe the size of a single partition with a 32-bit LBA field. Ergo, with an MBR table, you can have a max part size of 2TB. You can have 2x 2TB partitions on a 4TB disk, but that's pretty much the end of the road. Your only alternatives are to use GPT or …

How hard can it be to set a GNU make flag equivalent in VS... uh. Well hold up there - a make flag isn't the same thing as a preprocessor definition. Visual Studio is a compiler/editor, GNU make is a build system so they perform different functions. The VS equivalent to make would be nmake which …

It means it's already being defined somewhere else, in a global header file or something similar.

you don't need 300 MBits per second bandwidth. The maximum bitrate for Blu-ray Disc movies is 48 mbps. that and a PCI bus is 133 megabytes per second (300 mega bits = 37.5 Mega Bytes) Again, the Blu-ray bitrate is only for the compressed data - the decoder card has to send the decoded raw frames …

They spent all that money on motion capture, having the protagonist stand stationary would be a waste.

openglnb is exactly the same as opengl but with nearest neighbour (i.e. integer scaling) instead of bilinear filtering. Not sure what your definition of "integer scaling" is, but duplicating rows/columns is what it does when enlarging images.

Given whole-integer scaling is straight forward, more accurate on modern high-DPI displays (versus the existing double-every Nth line method), can be implemented along side the current scaling methods without influence on their performance or function, and doesn't require exotic underlying …

Start DOSBox (without booting into MS-DOS), mount the image and the host directory you want to copy files to/from as different drives.

You will encounter the same problem you posted above ("Setting excute permission on the code cache has failed"). The scaler has nothing to do with it.

That error would happen for either core=auto or core=dynamic regardless of any other settings. It's not heap corruption, it is the OS not allowing the dynamic core to map memory as both writable and executable.
