GCC has pretty handy builtin for that sort of things, often reduces to a single opcode on the target processor Signed-off-by: Michel Pollet <[email protected]>
Allow Makefile to define BORDER_WIDTH Signed-off-by: Michel Pollet <[email protected]>
Use __attribute__((packed)) for gcc, so make sure these structures are byte aligned Signed-off-by: Michel Pollet <[email protected]>
This adds support for scaling the window of the emulator. On 4K screens, GSport window is really tiny and unreadable. This implements another stage to the rendering using the XRender extension with a scaling transform. This appears to work with or without shared memory Also, modifies the Makefile to easily switch scaling on or off -- technically if could be made configurable at runtime too, for the moment the constant is passed as a #define Signed-off-by: Michel Pollet <[email protected]>

Anyone knows if this project has been forked into something that accepts PRs? it's been nearly 3 years now... |

Hey, good to hear from you again! This one somehow escaped my notice. I'd say "we still accept PRs," but I see what you mean here. :-) The upstream KEGS project is here, but Kent doesn't do GitHub, so contribution is a little more old-school: I'm maintaining a GitHub-based mirror of it to make creating patches easier: |

On a 4K screen, GSport window is /tiny/ -- this PR adds support for scaling, by adding support for rendering via the XRender extension using a scaling transform. It should be accelerated on pretty much any hardware these days, so has no real impact on performance.
Technically this makes the scaling configurable at runtime, but at the moment it is #defined as x2. I tried to minimize impact on existing code.
This PR also contains a few little fixes for modern GCC, for example there is a commit to use __builtin_bswap; it also force align the prodos.h structures, as that wouldn't work on 64 bits systems at least using gcc.
