small cvs update :) now it's faster (15-20 fps on gltest), and runs Dan Potter's reverie! (but with some broken textures). screenies: http://alumnos.utem.cl/dcemu/images/reverie1.png http://alumnos.utem.cl/dcemu/images/reverie2.png http://alumnos.utem.cl/dcemu/images/reverie3.png http://alumnos.utem...

hi, just in case someone is using dcemu for devel/testing, i commited some code that enables a serial output window, for debugging purposes. should be a bit faster (but still s-l-o-w). i'll try to make it work with more KOS homebrew, compatibility is still very low. homepage: http://alumnos.utem.cl/...

the gcc compiler that you get with cygwin compiles for x86, not sh4. you need to build your 'own' sh4 compiler (sh4-elf-gcc) from the gcc sources. check the tutorial at http://www.hangar-eleven.de/en/devdc-index.html.

to get a good disassembly with source code, try using sh-elf-objdump -S file.elf
never tried the gcc trick described earlier...

a few games initialise 3d hardware and then use the framebuffer (mostly KOS-using homebrew games).

i'm currently doing some work related to how the emulator handles the framebuffer. now i'm creating a GL texture for the framebuffer and GL_QUAD'ng it to the screen, it's a bit slow but it'll work when both 2d and 3d are used (which is currently broken, right now when the emu does any 3d it shuts do...

I don't have implemented DMA transfers yet, so that's why it doesn't work :D store queues are implemented though, that's what KOS use in most of the demos anyway. once I figure out how DMA works (hint: HELP ME! :) ) i'll implement it. also if anyone that works on DC software tries his/her software i...

try to make the dc.iso using an 11700 offset (like a AUDIO-DATA selfboot, echelon style): mkisofs -C 0,11700 -l -o dc.iso DIRECTORY it works with Wowpack :) the selector looks fine but when any of the wowpacks is loaded the right side screen gets corrupted, don't know why. also linux-dc (that old 20...

the #define OPENGL stuff is "deprecated" :) in windows when the emulator switches to 3d it stops updating the framebuffer. the emulator is creating an SDL surface with the specified framebuffer format for every framebuffer update. the problem is that if there's 3d going on (like vertex reg...

screenshots from dcemu running 'efecero' beta 3: (avilable in homebrew.dcemulation.org) http://alumnos.utem.cl/dcemu/images/efecero1.jpg http://alumnos.utem.cl/dcemu/images/efecero3.jpg it's barely playable but it works. that game doesn't seem to use 3d graphics but it's a game anyway and it WORKS! ...

try using sh-elf-objcopy -O binary file.elf file.bin
sh-elf-objcopy is part of binutils (when crosscompiling for sh-elf)

try putting a big file (dummy) when making the image. my burner produces coasters if the first track is too small, happens with dcload-ip too (very small). just put some mp3's or a movie or whatever (100mb worked for me). name it like '0000000A.DAT' so it's at the beginning of the disc.

CVS is now enabled! http://sf.net/projects/dcemu A very talented guy made an integrated disassembler too. Screenshots from today's CVS: http://alumnos.utem.cl/dcemu/images/tunnel.png http://alumnos.utem.cl/dcemu/images/wowpack.png both are very slow, but in wowpack you can actually move the cursor :...

used to post updates on the programming forum, hope that here is more appropriate!

Now with 3d! :) pvrmark: http://alumnos.utem.cl/dcemu/images/pvrmark.png pvrmark_strips: http://alumnos.utem.cl/dcemu/images/pvrmark_strips.png If someone does know how to overlay a 2D SDL surface on top of the screen, please email me! currently I can do 2D OR 3D, but not both on the same screen. Do...

since I don't have a bios dump or the coder's cable (to 'legally' obtain one), I had to 'build' the font from a Truetype font, and fake the bios call. well, emulation IS terminating after some seconds. does anyone knows when are maple interrupts produced? when scanning for devices? one int for each ...

cool, thanks! how much time does that screen lasts? and what happens next? (iven't checked the bfont source code). emulation goes nuts 1-2 seconds after that screen appears.

i had one, but one month ago i managed to kill the laser while cleaning the DC.
here in chile a used DC costs US$100. found a brand new DC in a store nearby, US$150. next month i'm buying the new one.

i've just made a new release, if someone cares. check : http://alumnos.utem.cl/dcemu Screenshot from bfont.bin in KOS 1.2.0 (probably the colors are wrong, I don't have a DC) http://alumnos.utem.cl/dcemu/images/bfont.png Currently i've problems with the interrupt controller. I'll start doing some 3d...

yep, you're right:

XOR Rm, Rn -> Rn = Rm ^ Rn
