- blackjack75, on 10/12/2007, -2/+39I'd like to make a comment about java's slow startup time but my jSacarsticCommentGenerator hasn't started yet.
- Caps, on 10/12/2007, -1/+36because he already has the computer and doesn't need to buy an Xbox...
- afsina, on 10/12/2007, -14/+27waiting for the first idiot who makes a java-slow joke or comment.
- dunezone, on 10/12/2007, -2/+15Format the A: and C: drive and then reboot...
- lcmatt, on 10/12/2007, -0/+12What the hell is that video?
- GMorgan, on 10/12/2007, -0/+11Yeah a JS x86 emulator might manage to run hello world coded directly in ASM.
- fyrehart, on 10/12/2007, -0/+10i formatted c
no mario for me
tried to exit shell
and it gave me hell
refreshed the site
willed it with all my might
but to my dismay
there are no files in c, just in a. - ichigosama, on 10/12/2007, -8/+17The next logical evolution of this is trying to get a Linux distro or a Microsoft OS to run, 3.1, then 95 then 98, etc etc etc... It would warm my soul to see Vista or XP running in a JRE, ignoring obvious speed issues with the runtime, the technology itself would be interesting.
- SenatorPenguin, on 10/12/2007, -0/+9I'm pretty sure you don't need an Xbox to run Doom; it's been ported to just about anything that has a screen, buttons, and isn't welded shut.
- inactive, on 10/12/2007, -1/+10If you have a powerful computer you can try doomsday engine, it uses the original doom wad files, plus extra content to give you a kickass OpenGL remake of doom. http://www.doomsdayhq.com/
- mercurysquad, on 10/12/2007, -1/+7Now we need someone to compile the Java code into Javascript using the Google gwt compiler. Then we could play DOS games purely in our browsers.. wheeee. :-b
- gamerzworld, on 10/12/2007, -0/+6no its not.
type
"C:'
"cd LEMMINGS"
"lemmings.exe" - haid, on 10/12/2007, -0/+4Yeah, like the X86 on your cell phone.
This is an infrastructure piece for the future.
It makes sense if you project forward a year or two.
What else am I going to do with my 8 core cell phone? - brianez21, on 10/12/2007, -1/+5You can't fdisk the A: drive since floppies don't have MBRs =P
- fLUx1337, on 10/12/2007, -1/+5wtf......why aint there no games?
I just get "Volume C: is pwned" lol - ChillyEli, on 10/12/2007, -0/+3Can't play Keen properly.
Requires the ALT key to shoot my raygun and use the pogo stick.
But pushing alt opens up my Firefox menu.
This makes me sad :( - cbergeron, on 10/12/2007, -0/+3Prince of Persia - WOW That brings back some serious memories... THat game was awesome...
- jmazzi, on 10/12/2007, -0/+3jetpack!
- jellomizer, on 10/12/2007, -0/+3What people need to realize that Java is its own byte code emulating x86 (some say roughly say an other bytecode) then being transfered back. So No you will not get native speed, Or even close to native speed. But with Mores Law in effect it will be probably be about as fast as a system, 10-12 years ago. A Late 486 early Pentium. For the bulk of users this is kinda slow but it is good enough for a lot of tests and running older applications. Why Java? Well unlike VMWare which needs the native processor to work. Boche normally requires a person to download it recompile it (Hoping the recompile works on their system). Or a Java Applet which you can just click on the browser. For people who need a quick Dos Box to scrap it is great.
- kewlito, on 10/12/2007, -0/+3LOL, same here
- daofma, on 10/12/2007, -1/+4Many DOS programs don't work well (or at all) on XP.
- tamat, on 10/12/2007, -4/+7cool, my european keyboard has the ':' character in other key and the emulator doesnt support it, so I cant change to C:
Simply brilliant. - mjhamilton, on 10/12/2007, -0/+3"open c:/brain/old *****/thingsihopednottoremember/doscommands.exe"
"Bad command or file name"
Dammit, I just drank this file away yesterday! - ropers, on 10/12/2007, -0/+2How to play your own old DOS games with the JPC emulator:
These instructions are for an Ubuntu Linux system, but should work for most UNIX-like OSes. Adapt as necessary. You may have to use sudo or be root for some of the commands.
; if you don't have curl, install it first, but I think it's included -- grab the JPC file to begin:
curl -O http://www.physics.ox.ac.uk/jpc/JPCAppletObfs.jar
unzip -l JPCAppletObfs.jar
; assuming /mnt/img exists:
sudo mount -t auto -o loop,offset=32256 dosgames.img /mnt/img
; now cd /mnt/img and monkey around with the DOS C: drive; copy your stuff onto it (may require sudo), free space permitting, etc. etc. -- once done, cd out of the drive and do:
sudo umount /mnt/img
; then add dosgames.img back to JPCAppletObfs.jar (I did this with Ubuntu/GNOME's Archive Manager/File Roller, so I don't have a command line handy. It's prolly easy to do w/ the command line as well.) -- finally, run the emulator:
java -classpath JPCAppletObfs.jar org.jpc.j2se.PCMonitor - ropers, on 10/12/2007, -0/+2No, you're not. If you tried you're a budding hacker. Because it proves you're curious and trying to push the limits. That's good. All that's missing is putting in the mental sweat of reading documentation, man pages, and persistently trying and figuring stuff out. If you do that and stay at if, you in time will easily trump the skillset of posters such as the above, whose sneering, slobbering disdain betrays his lazy hubris and his inability to see things from The Other Guy's point of view. We're all n00bs at most things, and we've all once been n00bs at everything. It's the intellectual laziness associated with the belief of knowing umpteen times more than the next guy that's an impediment to personal development and societal progress, not the fact that one knows very little and is starting to experiment.
- Latka, on 10/12/2007, -0/+2Floppies CAN have an MBR
- Sophistifunk, on 10/12/2007, -0/+2*AHEM* That's prince -megahits to you, mister!
- dominasian, on 10/12/2007, -8/+10I still have a windows 3.1 computer that i use for the sole purpose of playing doom. Besides he graphics that game is still so badass
- mister711, on 10/12/2007, -0/+2Why is it using 100% of my CPU for a Java window?
- ropers, on 10/12/2007, -0/+1Read this page then. Carefully.
- ropers, on 10/12/2007, -0/+1because emulation is computationally expensive?
- Sakkath, on 10/12/2007, -0/+1Appears that was me, didn't see what you said :).
- ropers, on 10/12/2007, -0/+1"format C: /u /autotest > nul" doesn't work. It appears FreeDOS hasn't implemented MS-DOS' undocumented format /autotest parameter. Oh, that one was SO much fun...
(http://www.textfiles.com/hacking/MICROSOFT/dosundoc.txt ) - gfixler, on 10/12/2007, -0/+1There are plenty on drive A! I'm playing KEYB.EXE right now. Oh, the memories.
- ropers, on 10/12/2007, -0/+1...and whaddayaknow, the old NFO files by THG are still online at textfiles.com:
http://www.textfiles.com/piracy/HUMBLE/
You prolly need a code page 437 compatible viewer though, because of all that ASCII art, cf. http://en.wikipedia.org/wiki/.nfo
And if more nostalgia strikes you, you can always watch the BBS documentary: http://en.wikipedia.org/wiki/BBS_Documentary - Shenaniganz08, on 10/12/2007, -0/+1ohhh i have click on it to type.. nice
what the hell since when can't mario jump on koopas to kill them ??? - AaronMT, on 10/12/2007, -0/+1This is very nice. I love the JVM.
- X-Cruciating, on 10/12/2007, -0/+1Play mario and press "B" twice and there it is! You can see "PROCEDURE Level_Initialization BEGIN . . ." Whoa! Let's debug this now :)
- ropers, on 10/12/2007, -0/+1type help in the lemmings dir to see how to play w/ keyboard
- astrotrain, on 10/12/2007, -0/+1Need more Carmageddon ...
- ropers, on 10/12/2007, -0/+1In Ubuntu 6.10 w/ Firefox, I cannot get keyboard input into JPC to work reliably. That means I can't type anything into JPC. Very frustrating. I've tried Sun Java 1.5.0 and 1.6.0. When I initially load Java and JPC after restarting Firefox, JPC has keyboard focus. However, once I move focus away to move the scrollbar, so I can actually see the entire JPC window, JPC loses focus and whatever I do I can't give it keyboard input focus back.
Does anybody have a similar problem and/or a solution? - ropers, on 10/12/2007, -0/+1If you really want to force it, empty your browser cash, close and reopen your browser, then revisit that site and your should be golden. That should work on all operating systems.
Even if you somehow fail to get things to work on your PC, there's no way you could have messed up things on the server by doing what you did, so no worries. - ropers, on 10/12/2007, -0/+1The Java Dosbox runs on your local machine, after copying itself from the server to your machine. You can screw with your local copy however much you like, it won't affect what's on the server.
- tech42er, on 10/12/2007, -0/+1Won't work in Vista. Then again, a lot of stuff on the web doesn't (using Firefox btw).
- superzorn, on 10/10/2007, -0/+1Sounds interesting... I bet this article was here about a year ago. http://travelsphere.blogspot.com
- Bisqwit, on 10/12/2007, -0/+1I can't type / or : in that emulator. shift+7 (where I'd produce / in a Finnish keyboard) produces & (USA mapping?), and the key next to right shift produces - (Finnish mapping?).
Same for the colon: shift + the second key from right shift (where I'd produce : in a Finnish keyboard) produces > (USA mapping?) , but the key next to L produces nothing (Finnish mapping? Doesn't recognize รถ).
Hence I can neither type "dir /w" nor "c:" - ropers, on 10/12/2007, -0/+1For similar Phunn4Y Schtuff, try http://www.masswerk.at/jsuix/
Or, if you have a Linux shell account, install GoboLinux rootless (http://www.gobolinux.org/?page=rootless ) and do all those things that you never thought you could do without being root. Happy days. - ray73864, on 10/12/2007, -0/+1ouch, perhaps typing 'format c:' and then 'format a:' wasn't such a good idea, cos now i can't even get the thing to work anymore :(
I hope it wasn't a real server, cos if it was then giving mere mortals access to the 'format' command was a very bad thing.
and yes, i did press the refresh button on the browser, and even closed the browser and re-opened it, and it still wouldn't load it up, kept coming up saying it couldn't find the boot stuff :( - ropers, on 10/12/2007, -0/+1Workaround:
1. Copy the below html code to a .html file on your local machine and open that with Firefox.
2. Don't click away from the JPC dos box.
(This html page only includes the dos box, do there should be no need for scrolling that will make the JPC dos box lose focus.)
The alt key however, still does not work. **sob** Commander Keen **sob** If you ever type edit in the dos box, you won't be able to exit that program.
