Although it does seem like a good idea I think using a capture card may be even better. You will be close to the PC.

As there is no source code I could not check if you are doing any integrity checks but if you are not you should be. For example maybe a crc32 for every one kilobyte of data.

I have heard multiple reports of this and I am not sure what causes the issue. I tested in on a windows xp virtual box and it ran just fine for me. I believe if it were a DLL error that you would get an error message.

Well FLTK is more lightweight and I think easier to use. I have not bothered with wxWidgets or QT as FLTK has been good enough for me. I am not saying that I am incapable of using them I just have not had a use for them yet. The only disadvantage to FLKT is that it does it's own drawing instead of u...

I can program GUI applications that are cross platform you can see an example of my work here http://gendev.spritesmind.net/forum/viewtopic.php?t=1392 I do not think programming a GUI application is any more challenging that any other type of programming. I use fltk which is very easy to use. If you...

I too would like to know but I was just thinking you say they used the three letter sequence according to https://www.gnu.org/licenses/gpl-howto.html There is no legal significance to using the three-character sequence “(C)”, although it does no harm. I will try and verify if that is really true how...

You know, I would not even worry about it. Sega does not appear to have any financial interest in GEMS.

Admittedly I have not personally made an example however pretty much any side scrolller on the sega genesis/mega drive features scrolling. You may want to check out viewtopic.php?t=1373 it contains an sgdk example of scrolling.

Well you give no definition of what "large" is. You can actually configure how large of a plane the VDP can hold. I googled this real quick and found http://md.squee.co/wiki/VDP#.2410_-_Plane_Size So if your dimensions exceed the size you specified you will need reload parts of the tilemap as the pl...

Well I just use vim. Out of the box when loading a file you can type :set ft=asm68k and syntax will be highlighted. Then you can use simple keyboard commands like gd to go to the definition of the subroutine. It should work with local labels too. As for seeing what registers are modified in a subrou...

Yes it is very easy. This is a bit more fancy generator and is only 31 lines of code. It generates fixed point integer tables. #include <stdio.h> #include <stdlib.h> #include <math.h> /* Compile gcc main.c -O2 -o sinetab -lm */ int main(int argc,char**argv){ long n,i; double mul,div; FILE*fp; if(arg...

Yes levels are constructed using smaller blocks and larger chunks. In the sonic games levels are constructed like this tiles->blocks->chunks->chunk layout. In all sonic games blocks are 2x2 tiles large. In sonic 2 and 3 chunks are 8x8 blocks in size however sonic 1 uses chunks that have the size of ...

I recently started keeping a change-log so that what has been improved is apparent https://github.com/ComputerNerd/Retro-Graphics-Toolkit/...
