Yes, SHR should be the fastest way to divide by powers of 2, without resorting to ASM.
Ages ago, when I compared in FBC 0.18b (?), SHR was ~15% faster than using the equivalent division operator.

Multiplying by the reciprocal of the divisor is another way to avoid slow division.

@marcov
Thanks, that's good clarification on the C64.
And is starting to refresh my memory.

@squall4226
Hope you get better soon.
Your project sounds promising.

Amazing Joshy.
Thank you for your effort in this conversion.

On Raspbian, the installer worked perfectly.
Then, to compile with fbc, ld needed its dependencies (ld: cannot find -lncurses):

sudo apt-get install libncurses-dev

(apt swaps to libncurses5-dev, but works)

Looks promising.

Discarding the first 512+ bytes generated from the keystream generator in rc4.bas would make the implementation stronger.

@Joshy Yes, the brain I was given falls far short of yours (I've seen lots of your code, and respect it). I know almost nothing about the Commodore 64, except the 'general view' that BASIC on it was bad enough that assembler was often preferred - hence, I guess why you might be suggesting your C64 e...

These 6502 emulators may be useful: http://skilldrick.github.com/easy6502/ http://e-tradition.net/bytes/6502/ http://6502.org/tools/emu/ The best online emulator I used was http://6502asm.com , but unfortunately the domain seems expired.

Fast, responsive program, with a nice scale option. Neat code. Superb images by Dr_D. It doesn't max out a CPU core (like Yea Chess v.1.16, http://free-zd.htnet.hr/drazen/ and some others). Piece movement is perhaps too fast (easy to miss opponent's last move) and the program ideally needs a move lo...

Thank you TJF.

Geany is pleasant to use with FB (unless you want to customize the color highlighting).

You can use other language editors for editing such as CodeBlocks (C++), and perhaps KomodoEdit (web files), although functionality will be reduced.

Purists might go for customised vi/vim.

Cool example dodicat!

Perhaps a GUI for Crafty? It's one of the strongest open source engines.

Garvan O'Keefe, in his FB 3D OpenGL chess program, used at least one GNU chess library (the GNU opening book I remember, perhaps another one too). That helps to set up a strong opening for the program to build upon.

Nice example pestery - particularly because of your own directory recursion code.

I had missed your example in all the searches done for research - probably because it was 'line' rather than 'code' or 'directory' related.

I have found Vince de Campo's command-line source code counter very useful: http://freebasic.net/forum/viewtopic.php?t=16594 but wanted directory traversal for website projects (rather than dumping all files into a single folder in order to count). Content within multi-line comments also did not see...

Yes, 512 array elements, starting at 0.

Thanks Oz for spotting this - you're correct, p should start at 0.
