![]() Right now, the problem is that we don´t have user-friendly tools to make using cartridge folders easy. The code to handle both modes is cumbersome, and I did not wish to write it again. It further requires a manifest to describe the PCB functionality. It requires the cartridge-folder concept that is still in development. Input mapping is now more advanced and allows multiple bindings per input.īut there is one critical thing it no longer does: the new GUI does not load individual ROM files. You can now easily add (and remove) entire systems from bsnes with only three lines of code. With the same amount of functionality, the new GUI is 66% smaller than the old GUI, code-wise. It pulls all of this information from a vector of emulated system objects instead. It looks and functions exactly like the previous release, but it is built entirely on a declarative model: the GUI does not know about any individual systems that it supports. This release introduces a brand new user interface. Casual users should wait for the next release. I strongly recommend against Linux package maintainers updating to this build. As such, only the source archive has been posted. I am only recommending that developers use this version. This release is going to be unique from previous releases. Name the file "bios.rom", and place it inside the "Game Boy Advance.sys" folder.Ĭheck out project website for latest files and informations. There will not be any high-level emulation of the BIOS functions for obvious reasons. Note that you will need the GBA BIOS image to use this. At the very least, hopefully this will be helpful to other emulators. On a side note, thanks to Cydrak and krom's hardware testing, we do have a nice milestone right out of the gate: proper OBJ mosaic emulation, which seems to be a first. In the end, it turned out to be harder than expected: it took about a month to complete the emulation core, and it was only this quick due to extensive help from Cydrak who fixed numerous CPU bugs, emulated the affine and bitmap rendering modes, and also implemented the new GBA FIFO audio channel, among other things. And since the GBA uses an ARMv4 CPU core, it seemed like a good choice: we could improve the ARM emulation for the ST018, and emulate the final 2D-based Nintendo system. This processor ended up using an ARMv3 CPU core. You can expect about ~150fps on average with a Core i7-class CPU for now, but please note that I do intend to improve upon this performance in future releases.įor a bit of backstory: this is basically a byproduct of SNES ST018 emulation. The GBA is a more demanding system than the SNES, by way of a much faster CPU core and higher frequency audio. It's important to note that the GBA emulation has not been optimized yet. I'd of course love some help with bugfixes, if anyone is interested =) It emulates all GBA functionality with the exception of the link cable and ROM prefetch buffer, although being a first release, there are bound to be plenty of bugs lurking in the core. It's not perfect by any means, but it's one of the better first releases I've put out. As promised from the last news update, this release adds preliminary Game Boy Advance emulation. ![]()
