Frequently Asked Questions
Can I do X in Bintracker?
The answer is probably yes, though it might not be convenient do to so (yet).
Which platforms will be added next?
Probably some Commodore computers.
Will Bintracker support FM chips?
Any plans for Android/iOS support?
Not yet. We may support mobile devices some day but not in the near future.
I'm using a French/German/other non-standard keyboard layout. How can I change the key bindings?
Go to your Bintracker folder, and open the file
config.scm from the
config subfolder in a text editor. Find the line that says
;; (load-keymap "en"), remove the two semicolons, and change the
"en" part to
"de", or whatever layout you use. See the
keymap subfolder of the
config folder for a list of available keymaps. If no suitable keymap exists, you can derive your own by copying one of the existing keymaps and editing it.
Sound is choppy and/or lags. What to do about this?
"-nofilter" "-nomax" to the list of MAME default-args in
config/emulators.scm. If that doesn't help, another one to try is
"-autoframeskip". If that still doesn't help, add
"-video" "none" instead. Newer versions of MAME will complain about this, but it nevertheless fixes most cases of bad audio.
How do I enable the MAME debugger?
-debug flag to the list of mame64 command line arguments in
Why are there so many parenthesis?
What do those
It's syntactic sugar for
(quote ...) and
(quasiquote). To oversimplify a lot, quotation is Scheme's means of figuring out whether something is code or data. Normally expressions are considered to be code, and are evaluated as such when the interpreter encounters them. Quoting turns code into data.
Say you have defined the symbol
my-number to be
my-number at the REPL will return
1, because that's what the symbol
my-number evaluates to. Typing
'my-number on the other hand gives you back the symbol
my-number, because that's what the expression
(quote my-number) evaluates to.
` does exactly the same as the tick
', but allows unquoting within the (quasi)quoted expression. A comma
, indicates unquoting within an expression following a backtick. So
`(my-number ,my-number) evaluates to the list
There's also unquote-splicing, but you don't need to worry about that until much later.
