I can imagine. I'm not getting one anyway.
Amazingly though, I just tried Xenon 2 Megablast, and however incredibly slow it is, it does work. :) |

bah, Xenon 2 is an ST and Amiga game. It stunk in DOS, and CaSTaway is fast :) For Civ, use CaSTaway as well.
DOS.. Wizardry 7, Eye of the Beholder, Dune 2 .. woowoo :)
DOSBox usually performs badly until you hit about 600MHz or so; how does she fare on the poor PSP?

I've uploaded a new binary fixing the vde194 crash. Here's the change, it's self explanatory.
| Code: | @@ -240,7 +254,7 @@

Yeah, I had a few Atari STs during the best part of my teens and later an Amiga as well. I know Bleem is the best emulator in existence but I couldn't get those guys to port it to the PSP or give us the source. The Atari is extremely emulateable, as CaSTaway also shows, and it is the only one for which most ROMs are actually legal and free of charge, including TOS ...
You can play Civ on the SNES emu also btw. :D
She doesn't fare too well on the poor PSP at the moment, because she's not being optimised or anything.
I think she might actually do well in theory though, if someone is skilled enough to use the Media Engine, a.k.a. MIPS R4000 number 2, to say emulate the main processor, and use the main MIPS R4000 to emulate the rest, or something like that.
But that'll probably be hard work.
@crazyc: looks good. |

I found your problem related to 'Slow games' AS an expert with dosbox. Im guessing that the CPU cycles arent high enough
put them about 10000 (in dosbox.conf) |

I have downloaded and implemented the files from that are provided form here
http://www.niwra.nl/psp/dosbox-psp.zip
http://home.wi.rr.com/crazyz/dosbox.patch How do I install this patch
http://home.wi.rr.com/crazyz/stat_trunc.c How do I install these library files
However I am having problems with operating Dosbox. Essentially they are the same problems that Arwin was having i.e.
1. The p-srint combination does not produce a "Y" key.
2. The p-sprint "Enter" button does not appear to be acting properly.
3. No mouse input.
These problems are preventing me from using Dosbox effectively.
I have installed dosbox and was interested in running some small LOGO programs. PCLogo version 4 seems to run fine. The slowness of the emulation is not a problem since it allows one to see the logo commands slowly creating the desired patterns. Not having a Y key is a bit of a pain (so is producing the " code but it is posible).
I was also interested in running some very old flightsims of less than 1 meg on size but cannot get past the splash screen for each sim.
Would it be possible for someone to make available the latest dosbox with the patch in a 1.0 or 1.5 eboot format? Also, how do I install the patch and library files.
Thank You

| I'm using the .elf and .config files that crazyc put up in his opening post. I start these using File Assistant ++, but if you want them as a PBP I suggest picking up the ELF2PBP tool somewhere on pspupdates. |

Thanks Arwin and crazyc
Things seem to be working OK now. I now have a mouse and functioning Y key :)

I have downloaded all the files that phage13 had noted
however, I am completed lost. I don't even know how to make the dosbox run in my psp. Can someone please tell me what are the steps that I need to do in order to get everything right?
Thanks.

hi uesugi,
You have two options.
Option1. Download the files that crazyc has provided in the third message in the thread. The first will be saved as dosbox. You must change the name of this to dosbox.elf
The second file will be saved as dosbox.conf
Create a folder on your psp called dosbox. Now place the dosbox.elf and dosbox.conf in this folder.
Now go to, say, www.pspudates.com and download and install the fileassistant+++ programme.
Run the fileassistant programme and select the dosbox.elf file. You will then be given an option to run that file. Do this and dosbox will start.
Option2.
Download the 2 files provided by crazyc and rename the dosbox file to dosbox.elf as before.
Download a the elf2pbp programme which can be found at pspupdates.com
Run the elf2pbp programme and convert the dosbox.elf file into an eboot.pbp file. Now use the kxploit programme if you need to run dosbox with firmware1.5. The dosbox.conf file goes in the dosbox folder along with the eboot.pbp file
Option1 is the simplest. |

| Sorry if this question has already been proposed, or if I unwittingly say something very nooby, but is Dosbox for the PSP still under development? It sounds like such a great idea. I'm thinking it would be awesome to play some of my old dos games like Willy Beamish, Wing Commander, Ultima, Rise of the Dragon, etc., but is that hoping too much from the PSP? |

I've had problems getting it to work after I upgraded my toolchain, I am still working on it at a slow pace though. I don't know if it will ever be fast enough to play any of those games. |

I myself haven't been able to get a binary of dosbox to work, but it's good to hear there's a few fixes out there.
How fast do you think it would be for say games like commander keen and the like? Old school side scrollers....
Also, eventually, will it be possible to map certain buttons (d-pad to arrow keys, ctrl to x, alt to o, etc) using a config file?

You could play rise of the dragon via the sega cd emulator.....
I do.

| Good luck with your DOSBox project CrazyC. I am really looking forward to a new version. I really could use a psprint pic guide (there are also some really nice new keyboards you could implement being made at pspupdates) inside the emu and some increased compatibility. I'll donate if your in need. I don't know what to do with myself trying to get this to happen. :( |

Hi!
JUst wanted to ask what prevents u crazyC from creating a more compatible and more fluidly running version?
I mean this beta from '05 seems to work pretty nice, but I actually can't run ANY game needs 33 mhz ... so this DosBox is pretty useless. I mean of course it needs alot of power to emulate even a 33 mhz unit, but this should be realizable. I actually can't even code one line and I appreciate ur work alot, but why did u stop working on it? I think it is pretty sad that u don't develop this project any further. Back in the days there were alot of very good games that I'd love to see running on the PSP. |

Now that i've got a working toolchain again, I've posted a new patch and binary at the earlier links. Threading the input code provides a nice speedup, the Warcraft 2 main menu is reached in about a minute. To build it you'll need this ftruncate implementation and to run it a fix needs to be made to SDL. In the SDL video code, if a video mode change occurs to a paletted mode when the palette memory was already allocated, this->hidden->tpsm will be set to GU_PSM_8888 not GU_PSM_T8.
| Code: | int ftruncate(int fd, off_t length)
{
int ret;
SceOff oldpos;
if (!__PSP_IS_FD_VALID(fd)) {
errno = EBADF;
return -1;
}
switch(__psp_descriptormap[fd]->type)
{
case __PSP_DESCRIPTOR_TYPE_FILE:
if (__psp_descriptormap[fd]->filename != NULL) {
if (!(__psp_descriptormap[fd]->flags & (O_WRONLY | O_RDWR)))
break;
return truncate(__psp_descriptormap[fd]->filename, length);
/* ANSI sez ftruncate doesn't move the file pointer */
}
break;
case __PSP_DESCRIPTOR_TYPE_TTY:
case __PSP_DESCRIPTOR_TYPE_PIPE:
case __PSP_DESCRIPTOR_TYPE_SOCKET:
default:
break;
}
errno = EINVAL;
return -1;
}

|

i have read alot and got the binary changed into an PBP.
Its working fine on my PSP. THANKS SO FAR CRAZYC YOU HAVE DONE A GREAT JOB SO FAR !!!! WOW !!!!
But now my next Question:
How do i implement the Patch, the ftruncate and the newlib ?
Or JimParis could you provide us with the new Binary, if you managed to merge them in ?
I have downloaded the Toolchain and gonna install it later on. But help would be appreciated! |

| I've posted a new patch and binary that fixes serious problems with unaligned loads and caps the framerate at 60fps. Also, joystick and mouse mode can be toggled with ltriggger+rtriggger+down+start. With this Commander Keen 3 is a bit slow but very playable. |

| Another new patch and binary. This one draws directly rather then copying the frame into SDL's buffer and disables those audio devices that are unused. Adlib emulation seems to crash occasionally avoid it for the moment (it also is rather slow so it probably should be avoided anyway). |

Would be nice to see some control mapping now, Im tempted to try dangerous dave out as it looks normal speed
examples : d-pad is standard up, down , left and right
analog for mouse
Square = Control
circle = Alt
X = Enter
Triangle = Space
L = shift
R = another key i may have forgotten |
