This is a wireless debugger for the Nintendo DS. It allows homebrew developers to interactively debug their applications running on a real Nintendo DS.

Things it can currently do:

- suspend the program at user-defined breakpoints
- step individual instructions, assuming the program has paused at a breakpoint
- step whole lines of source code
- inspect memory locations - and assuming a symbol table is present in the original ELF - variables and other structures can be read and their values can be changed
- inspect the state of all registers in the user ARM execution mode - including the program counter, link register, stack pointer and status register
- evaluate all types of ARM branch and condition instructions, allowing you to follow the execution of code properly in most circumstances
- it has a blacklist function, which defines which functions shouldn't be stepped into (when a b/bl/bx instruction is encountered). This is useful to prevent the debugger from stepping inside itself, or functions used by the debugger. If you do step into the debugger, it will probably get into an endless loop and hang.
- it can break on invalid memory access, signalling a SIGBUS message to the host debugger
- it can break when an invalid instruction is executed - this signals a SIGILL message to the host debugger
- both these exceptions destroy the original instruction in memory, so if you read the original opcode back from DS memory you'll get the breakpoint stub opcode instead. To get the real opcode, disassemble the ELF instead. If there's demand for having the real opcode left in memory I'll make the changes required to fix this.
- with minimal work, it ought to be able to co-exist with applications which use sgstair's wireless library

Thanks to the help of the people in #dsdev the display corruption bug has been fixed, shown below is the emulated Macintosh Plus looking for a startup disk.

Slightly corrupted output from the Macintosh Plus emulator MiniVMac, but proves that early macintosh emulation is possible.
I will be working on this while I try and track down a sound bug in wolfenstein 3d and get a few more features in before another release

Rockman ZX

Rockman ZX (RMZX) is the first original Megaman game to hit the DS, it is an
old school 2d action packed platformer and a sequel to the GBA Zero series.
This review is a non spoiler one targeted at people that may want to import
the game since it is out only in Japan for now.

Presentation/graphics 10

A perfect score, RMZX has the most beautiful and detailed backgrounds,
character sprites and animations i have ever seen on the DS.
Even better than Castlevania, it is the best you can get for a 2d game, while
not using the DS 3d capabilities, ZX gives it a run for it´s money on sprite techniques.
Also to note are the gorgeous special effects, anime cutscenes and the full voiced
ingame script.

Music/sound effects 9

The music set the stages tones just fine, melancholic on the raining area,
fiercy on the burning one and so on...
The sound effects do their job well, along with the voices on combat, they
help you get the feeling of a powerfull war being waged upon you.
Once again, all the dialogue is voiced and it will be dubbed again for
the English release.

Gameplay 10

RMZX is a very fun game, it starts with the main character, Vent or Aile,
merging themselves with the Biometal Model X, that is no more than the
power and memories of Megaman X of the X and Zero series, after that you
go finding models of Zero and the "Guardians" from Megaman Zero series.

The thing is that each model has it´s own set of abilities and you can change
models on the fly, that mix of different styles combined with different perils make the gameplay shine.

You can go with model Zx and come to a platform you can´t reach, change to model Hx and
jump-dash with it, while at the high ledge, you see an enemy below, no problem, change to
model Fx, edit your shots trajectory and nail the pesky guy from your safe place, brilliant.

The stages come on a Metroid-esque style, much like the later Castlevania games, you go
from area to area, accomplishing missions and defeating the bosses, each model comes with
a card key to unlock doors color coded with them while the innate abilities of the models
help you reaching places that you could not do before acquiring them, the map could be more
organical though.

The Biometals are acquired from defeated bosses as any Megaman game, the catch is that they are
on a specific place within the boss body, while hitting there causes more damage, it also damages the Biometal, making it more expensive to repair, yes, you will use energy cristals to repair your Biometals,
so the question is, do you want to risk losing a battle to save E-cristals?


DS factor 7

It utilizes the lower screen for the Guardians Biometals, each with a distinct effect, the 3d engine is not used but one of the less utilized DS feature is very well developed here, the GBA slot.
If you insert MMZ3 or MMZ4 you can battle 8 more bosses from those games,
it is a nice way to take the dust out from the old GBA carts.

Learning curve 7

Well, it took me 5 secs to learn it but, hell i am a hardcore Megaman fan!

For the casual gamer, it may take some 15 minutes to get the hang of it,
but mastering all the models may take some 5 hours of your life, i recommend
for newcomers to the series to use the easy difficulty setting, if you can stand the heat, go normal.

Lasting appeal/game modes 8

It can last very long if you want to unlock everything, find all the data disks, play both Vent and Aile.

EDIT: there are minigames, don´t know how to unlock them, but if you go to the arcade on area C-2, one of the machines will be on and you´ll get to play a soccer minigame for 20 e-cristals, since there are more four
machines, it may have more minigames.

Final considerations

This could be very well considered the best Megaman game ever and it is.
It is a must have for all the die hard fans and a very good game for the newcomers, one of the best of the DS.
What more can you ask, anime cutscenes, full voiced dialogues, big game, multiple gameplay styles, it has it all.
