vnf,runrom: detect bad data access

2026-10-09T19:45:05Z

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")).

xixanta: Add an hint for the ending of data labels

2026-10-09T19:31:33Z

Some raw labels may point at a bunch of data laid out with the .byte family of statements. Add hints for each of these labels so we also have a range for them. This way, tools like 'vnf' might be able to detect bad accesses and these sets of data. Signed-off-by: Miquel Sabaté Solà

Don't error out on conditional .include

2026-10-06T15:33:16Z

The hard requirement that an .include statement cannot be inside of another block was, in the end, a bit short-sighted. Imagine the following block: .ifdef DEBUG .include "debug.s" .endif This is perfectly sound-looking code, and it should not be punished as the developer is doing something that is not bending the assembler in weird ways. Hence, just nuke this check. Signed-off-by: Miquel Sabaté Solà

readrom: add support for default expansion device

2026-10-06T15:27:50Z

The 15th byte from the NES 2.0 header was wilfully ignored, but it can be relevant to the end user. Hence, add support for it in the 'header' library, and add the frontend code into 'readrom'. The point is not to support every single thing out there, but I have added the stuff that I thought was most relevant, and we can add more items to it whenever the need appears.

header: add more information on unkown mappers

2026-09-19T20:06:00Z

In particular, allow to optionally add the mapper and submapper ID that was found, so it can be displayed to the user. Signed-off-by: Miquel Sabaté Solà

xixanta: simplify evaluate_hexadecimal()

2026-09-15T16:03:36Z

The 'size' variable can be initialized directly from the value we get from the match statement below. I was probably thinking more on the style of C, but the latest Rust stable channel complained about this. Signed-off-by: Miquel Sabaté Solà

fuzz: change names to have dashes instead of underscore

2026-09-15T16:02:43Z

From the latest update of Rust's stable channel, this was raised as a bad format for fuzz names. Signed-off-by: Miquel Sabaté Solà
