byuu says: Most notably, this release adds Nintendo DS emulation. The Nintendo DS module was written entirely by Cydrak, so please give him all of the credit for it. I for one am extremely grateful to be allowed to use his module in bsnes. The Nintendo DS emulator's standalone name is dasShiny. You will need the Nintendo DS firmware, which I cannot provide, in order to use it. It also cannot (currently?) detect the save type used by NDS games. As such, manifest.xml files must be created manually for this purpose. The long-term plan is to create a database of save types for each game. Also, you will need an analog input device for the touch screen for now (joypad axes work well.) There have also been a lot of changes from my end: a unified manifest.xml format across all systems, major improvements to SPC7110 emulation, enhancements to RTC emulation, MSU1 enhancements, icons in the file browser list, improvements to SNES coprocessor memory mapping, cleanups and improvements in the libraries used to build bsnes, etc. I've also included kaijuu (which allows launching game folders directly with bsnes) and purify (which allows opening images that are compressed, have copier headers, and have wrong extensions); both of which are fully GUI-based. This release only loads game folders, not files. Use purify to load ROM files in bsnes. Note that this will likely be the last release for a long time, and that I will probably rename the emulator for the next release, due to how many additional systems it now supports.

|
|
//nall::property implements ownership semantics into container classes
|
|
//example: property<owner>::readonly<type> implies that only owner has full
|
|
//access to type; and all other code has readonly access.
|
|
//
|
|
//this code relies on extended friend semantics from C++0x to work, as it
|
|
//declares a friend class via a template paramter. it also exploits a bug in
|
|
//G++ 4.x to work even in C++98 mode.
|
|
//
|
|
//if compiling elsewhere, simply remove the friend class and private semantics
|
|
|
|
//property can be used either of two ways:
|
|
//struct foo {
|
|
// property<foo>::readonly<bool> x;
|
|
// property<foo>::readwrite<int> y;
|
|
//};
|
|
//-or-
|
|
//struct foo : property<foo> {
|
|
// readonly<bool> x;
|
|
// readwrite<int> y;
|
|
//};
|
|
|
|
//return types are const T& (byref) instead of T (byval) to avoid major speed
|
|
//penalties for objects with expensive copy constructors
|
|
|
|
//operator-> provides access to underlying object type:
|
|
//readonly<Object> foo;
|
|
//foo->bar();
|
|
//... will call Object::bar();
|
|
|
|
//operator='s reference is constant so as to avoid leaking a reference handle
|
|
//that could bypass access restrictions
|
|
|
|
//both constant and non-constant operators are provided, though it may be
|
|
//necessary to cast first, for instance:
|
|
//struct foo : property<foo> { readonly<int> bar; } object;
|
|
//int main() { int value = const_cast<const foo&>(object); }
|
|
|
|
//writeonly is useful for objects that have non-const reads, but const writes.
|
|
//however, to avoid leaking handles, the interface is very restricted. the only
|
|
//way to write is via operator=, which requires conversion via eg copy
|
|
//constructor. example:
|
|
//struct foo {
|
|
// foo(bool value) { ... }
|
|
//};
|
|
//writeonly<foo> bar;
|
|
//bar = true;
