Update to bsnes v024 release.

This is an interim release between some major changes to the video mode support, which may take a long time to complete. It also fixes a bug with CGRAM access timing, re-adds the Sufami Turbo load menu, and adds support for the ST-010 coprocessor, used by F1 Race of Champions. To load Sufami Turbo cartridges, stbios.bin must be placed inside a folder named bios in the bsnes folder. There is not currently a warning if this file is missing.
Update to bsnes v023r01? release.

byuu	9fd379613a	Update to bsnes v024 release. This is an interim release between some major changes to the video mode support, which may take a long time to complete. It also fixes a bug with CGRAM access timing, re-adds the Sufami Turbo load menu, and adds support for the ST-010 coprocessor, used by F1 Race of Champions. To load Sufami Turbo cartridges, stbios.bin must be placed inside a folder named bios in the bsnes folder. There is not currently a warning if this file is missing.	2007-10-01 09:03:44 +00:00
byuu	aabf52d678	Update to bsnes v023r01? release. Alright, I've posted the new WIP. Changelog: - CGRAM fix for WWF Super Wrestlemania - Updated to blargg's snes_ntsc library to version 0.2.2 - Added ST and ST dual cart loading menu options () - Redesigned the video mode configuration panel a bit -- let me know what you think () () - You have to set path.bios to an -absolute- path, ./ is currently broken and I need to fix that. So, set it to eg "c:/path/to/bsnes/bios" where stbios.bin is inside that folder. (**) - The video menu obviously doesn't do anything, it's just there for design advice / suggestions for now. You'll notice the icon is gone. This is because I built this version with MinGW 4, and I'm not sure how to add the icon to MinGW apps. You'll also notice it's ~6% faster on Core 2 processors as a result. The 16% speedup was only when PGO was enabled. But I can't enable that, because it causes bsnes to crash randomly. GCC gets too risky with its optimizations and ends up generating bad code (the GCC manual states as much, I'm not just trying to blame problems in my app on GCC here.) So, 6% is the best speedup we can do for now. Compare to v0.023 official if you like. You probably won't see the speedup on older processors like the Pentium IV. EDIT: it seems like that MinGW vsnprintf problem is based on DLL files on the local computer. Probably the MS VisualC runtime files. The WIP works fine on my home PC (WinXP Pro), but not on my work PC (Win2k). I'm going to have to stick with Visual C++ builds until I am able to completely remove all sprintf-style calls from the emulator. If you get an error about memory at 0xffffffff which cannot be read, you know why. Try building with Visual C++ if you have it, or maybe there's some way to upgrade libc DLLs that the app is binding to. Whatever DLL has vsnprintf is the one that needs to be updated, if at all possible. Here's what the video config screen looks like at the moment. [image] I tried putting the text at the top, that way there won't be any odd gaps between the text and combo box dropdown, due to different sized fonts on different platforms. [No archive available]	2007-09-25 14:20:00 +00:00
byuu	c9ca01fe20	Update to bsnes v023 release. I've recently fixed a bug in bsnes that I feel is serious enough to warrant a new release, even though little else has changed. I attempted to build this release with MinGW, but ran into problems with profiling and JMA support, so this release was built with Visual C++ once again. Changelog: - Fixed serious bug in S-SMP incw and decw instructions -- fixes sound bug in Emerald Dragon - Added Nach's MinGW fixes -- can now be compiled with MinGW/GCC3 or MinGW/GCC4 - Fixed const char* cast warnings in GCC 4.2, thanks to [vEX] for the feedback - Updated source to use latest libraries for libco, libui, etc. - Added new advanced options to adjust aspect ratio correction - Cleaned up source code a bit	2007-09-16 19:30:35 +00:00
byuu	becf122aaa	Update to bsnes v022r04? release. Ok, I've posted a new WIP with the Emerald Dragon bug fix. This time, I'm not posting the WIP publically. My last request not to link directly to the file elsewhere was ignored, and ended up on at least two emulation news sites (I won't mention names.) I'm not trying to be a jerk about it, I really can't spare that kind of bandwidth. If anyone has contributed any code or bug fixes, reported any confirmed bugs, or is an emulator author I've spoken to in the past, feel free to request a link to the WIP page from me in PM if desired. Sorry to everyone else. I'll have the new version out as soon as possible. > As for the AR advanced option, I think option 2 looks perfect. Done. I didn't add any sanity checks, so that people can have a little fun with it. It's not going to be a GUI option, so only advanced users can play with it anyway. Try setting a crazy aspect like 3:1 and play a platform game. It's guaranteed to mess with your mind. I also added the ... stuff, but I did not add the pause support back in yet. Not sure if that'll make the next release, because it requires some changes to the main loop functions that have been missing for a while now. I usually like to leave more of a beta testing window before messing with that stuff. > byuu, you may know this, but on the front page of your web site, the > link to your Philosophical Ramblings page is > "http://localhost/index.php?page=articles/philosophy". Hahah, oops. No, I didn't notice that. I must have copied the link from my browser instead of typing it manually. It's a stupid article, anyway. Didn't come out like I planned. I was also reading some comments by Miguel de Icaza (supporting patent pacts) and Linus Torvalds (bashing the hell out of C++ programmers), and came across an interesting comment that got me thinking. Basically that people who have any kind of notability really shouldn't go around talking about things outside their specific expertise, because it makes them look foolish when people take them too seriously (and people do) as those two comments by de Icaza and Torvalds did. Lucky for me I really _don't_ have any kind of notability, but it's a good principle to adhere to anyway. Stick to talking about what I know best. That goes against my whole personality though, so I probably won't change at all anyway. [No archive available]	2007-09-12 10:08:00 +00:00
byuu	1e130d7872	Update to bsnes v022r03 release. Double post! I've uploaded a new WIP, which I'll make public (only to this forum, please don't post about it anywhere else unless you mirror the file): http://byuu.org/files/bsnes_v022_wip03.zip This version adds all of Nach's MinGW fixes, updated libco, libui and libfunctor, cleans up the code that detects if the main window has focus or not (if not, ignore keyboard input), adds the new makefile target win-mingw-lui, finally fixes all of the char* conversion warnings with GCC 4.2.x (thanks [vEX]), and I'm sure there's more, but I don't remember. The ZIP includes a Visual C++ generated binary, but it also works with MinGW GCC4. It won't work with MinGW GCC3 because that one lacks a C99-compliant vsnprintf function. You can hack your way around that by editing src/lib/libstring_sprintf.cpp if you really want to use MinGW GCC3. You may also need to change the CC / CPP variable names. I went with the generic names mingw32-gcc and mingw32-g++, but the GCC4 binaries have -sjlj or -dw2 appended to them. You'll also need to set -I/path/to/directxheaders, or copy them all into /path/to/mingw/include, since MinGW seems to ignore the include environment variable. And finally, a bit of good news. It appears that MinGW GCC4 builds binaries that are ~6% faster than Visual C++. That means with PGO enabled, they should be at least ~16% faster than v0.022 official. If I can figure out how to hide the ugly terminal window in the background, I'll start making official releases with MinGW GCC4 from now on.	2007-09-08 08:41:18 +00:00
