squidgetx Releases Space Dash 1.2
Posted by Travis on 26 September 2010, 09:56 GMT

Screenshot of Space Dash squidgetx has released Space Dash 1.2 for MirageOS (or a MirageOS-compatible shell) on the TI-83/84 Plus. Space Dash is an Axe side-scrolling space platformer that features saved high scores, three-shade grayscale, and parallax scrolling. The object is to race through the levels, jumping over or shooting at obstacles to avoid crashing. Check out the animated screenshot on the download page to see it in action.

This game is pretty epic. I just judged the version for the Omnimaga contest (although I have yet to write down scores) and this is an awesome game. I'm glad the small bug was fixed in the new version and that it was finished. Nice graphics and pretty addicting. Congrats :)

Yeah last night I was hooked to it for a while :D

I was kinda hooked to Splut and Jump as well, but Splut had a key detection issue which made it a bit less enjoyable for me in its contest entry form D:.

I have about 7 more entries to check now :P

I liked the first version, I should really download this.

The Axe contest saw a lot of awesome games like this.

"...for MirageOS on..."
In the screenshot he runs it from the home screen.

Yeah I think it had to do with the fact the file was uploaded in the MirageOs directory.

The readme says: "and play via either MirageOS, DoorsCS7 or other compatible shell."

DoorsCS has Noshell features, doesn't it? Or he could be using CalcUtil or Noshell.

It does but the screenshot shows the nostub version. Since the source code is included, you can compile the program for the shell of your choice and even an APP if you got Axe Parser. I don't know if it works well in APP form, though. If it uses self-modifying code tricks, it certainly won't.

Oh, I forgot about how he used Asm( to execute it... right.

This games is not for MirageOS, as that posters above indicate. It's nostub and can be played in Doors CS 7, from MirageOS, or from the homescreen.

The screenshot is of the nostub version
The executable included with the zip is for MOS

Like kevin said, the source can be compiled with Axe to any shell you want (except Application, as this game using some smc tricks). I just chose MOS as the shell to have the executable run in for the release since MOS has the most compatibility with the current shells (I dislike Ion) lol

*Doors CS 7 has the most compatibility etc.

right, we discussed on irc but for people curious, I meant that MOS is the lowest shell that anyone will be using. DCS7, the other major shell, will be able to run it whereas if I compiled for nostub or pure DCS, one of the two wouldn't be able to run it

Yeah, because Mirage/Ion won't run nostub/dcs7 programs. I think some Ion programs crashes in Mirage too (like The Core Of Light)

I generally compile my programs for Ion, as then the programs can be run with Asm( or in any shell. =)

Strange... some Ion games won't run with Asm() or even crashes. Example is Ztetris.

Is it that much of a problem? It runs. It works. What else do you need from a game? Besides, you could just recompile it to a different shell--No Shell, Ion, MOS, DCS, or APP.

I was just replying to the comment saying Ion programs also runs nostub. I wasn't saying the shell is a problem.

To add to my previous comment, we cannot recompile existing games to other shells if the source is not available and/or if they are dependent on those shell routines, anyway.

They shouldn't run with Asm(); Ion contains a set of eight routines that the programs need in order to function correctly. :)

Ah ok, but I always thought "nostub" meant that the program absolutely have to be compatible with Asm(prgmNAME) syntax?

Axe doesn't use calls to shell routines and so Axe programs compiled to Ion can be run from the homescreen as well. This is becasue most of the shell routines are either not compatible with the Axe routines or don't take the correct input and output. This is all assuming you are not using inline assembly or libraries which can be used to make shell calls.

Ion programs *can* be written so as to be executable from the home screen (using the XOR A header), but it requires some care: obviously, you can't use any of the Ion libraries, you're limited to 8k, and you can't do writeback reliably, but there are some less-obvious differences between the way the homescreen executes programs and the way a shell would. So I can't really recommend it for most programs.

One point that's often missed about MirageOS (and DoorsCS) versus Ion is that MirageOS programs can use the MirageOS library routines regardless of how large the program is. Not true for Ion programs: the Ion libraries will only work if your program is smaller than 8k minus a bit.
