This function already took most of the arguments from the user anyways,
and the list of separate arguments was getting crazier to a point that
even clippy started to freak out.

vnf,runrom: detect bad data access2026-10-09T19:45:05ZMiquel Sabaté Solàmssola@mssola.com2026-10-09T19:45:05Zurn:sha1:f6df4314945c1d37d314a7c88553b97b23c748e9
This includes detection for:
- Stack underflows (it was theoretically already there but it had never
been properly tested).
- Load/store out of bounds for a given variable known via the .nasm/
directory.
- Load out of bounds on a set of data referenced via a raw label (see
commit aa5174fc055d ("xixanta: Add an hint for the ending of data
labels")).

runrom: regularize the output on report2026-10-08T19:56:43ZMiquel Sabaté Solàmssola@mssola.com2026-10-08T19:56:43Zurn:sha1:466dcce47cc1158d5d92a66119d4d89fe657e356
Make the hexadecimal values more cohesive and avoid having a
variable-sized line because of them.

Add an option for setting a cycle limit2026-09-08T15:32:08ZMiquel Sabaté Solàmssola@mssola.com2026-09-08T15:32:08Zurn:sha1:1601d0353342230a2a93baa6f008bc16a10137a1
This can be quite handy when it comes to checking that a piece of code
doesn't exceed a given amount of cycles, or when you are tuning a block
of code in order to make it go beyond the current amount of cycles.

vnf: add the 'Machine.halt_on_brk' field2026-09-07T21:03:55ZMiquel Sabaté Solàmssola@mssola.com2026-09-07T20:31:33Zurn:sha1:a17bd972a99007099057d7901b88732b22d08270
This allows developers to use 'brk' as asserts which can then be
debugged. This is true by default but it can be turned off via the
--no-halting-brk option from runrom.

vnf: add support for standard joypads2026-09-06T13:47:50ZMiquel Sabaté Solàmssola@mssola.com2026-08-29T22:06:39Zurn:sha1:ad77503d953302f22a621093ba359e24526892ec
This means adding constants so developers can actually trigger which key
presses are available at any given read, as well as a simple interface
that allows to add button presses and clear them.

Change the first argument of Machine::from() into a &Path2026-08-27T05:20:54ZMiquel Sabaté Solàmssola@mssola.com2026-08-27T05:20:54Zurn:sha1:698f12a7b4cf403a53e98d5bd3f7318e107079f9
This makes for a saner API, and some users (e.g. vnf-tests) don't have
to go over backwards to provide a parameter they already had as a
PathBuf.
