Sure deal.
Also, I think there's something worth noting. I've identified a potentially serious bug. Although the game has not crashed on me because of this, I just want everyone to be a little wary about it.
Upon exiting the game back to MirageOS, the size of each of the programs will read off the same size as Fishy. In addition, I've heard of reports of programs "unhiding" themselves in the shell. The current workaround I've seen would be to simply exit the shell and re-enter it.
I believe this bug, even if I have not identified the exact cause, is serious because it may indicate a buffer overflow of some kind, perhaps relating to the table routines. If someone were to test this program to determine if it is indeed writing to areas outside of its own bounds I'd like to know about it. Currently, the program uses SMC for its built-in table and variables, and writes to the appbackupscreen buffer for the sprite table.
As for what should be done by now, I suggest that each time you play Fishy, make sure that all things are archived, or ensure that the information on your calculator is appropriately backed up.
If you identify any additional bugs, I would like to know. Also, keep in mind that the most recent version (found somewhere, I dunno if I updated it to that) has a teacher-key issue fixed. |

Hi, I completely missed this thread before so haven't yet tried the game, but it looks fantastic. ;)
I don't have access to the source, but I've found strange things happening in MirageOS with my own programs, such as changing the case of program names, program names disappearing completely, sizes displayed incorrectly and so on. In my case it boiled down to modifying the various asmFlags. |

I don't mean to sound like a n00b or anything, but... does MirageOS actually *use* the asm_flags and expect the value of that to remain intact between program executions?
I ask that because I neglected to mention that Fishy also uses asm_Flag1 to store values.
And I'm also hoping that the problem with Fishy isn't any bigger than not having flags saved. I'll go and make those changes ...

Is the fish movement problem being worked on? Like where if I tap the up arrow my fish goes up one pixerl, if I tap the down arrow nothing happens.
TIHO: work on z80 heaven!

I believe I have the Mirage OS display bug handled. I preserved asm_flag1 (defined in the game as "Fish3Flag"  ) and the display bug seems to have stopped.
Also, I actually *noticed* the specified movement issue. The problem boggled my mind for an hour, but then I identified the specific run of code. I had a cheap way to fix it and the more expensive method. I chose the more expensive method since I believe more people would enjoy the game a little better if you could easily move the fish instead of having to hold the button to get the fish to move at all. I'm sure 26 bytes that was "wasted" would improve the enjoyment of the game.
Also, the source should be with the game this time around. Optimization would be helpful. See the attachment about the game and the source, while I wait for an update.

| Really glad to see the movement bug fixed. Although the mirage bug didn't bother me, I am glad nothing will happen in the future.(with mirageos) Good job Iambian. |

The secret to the DevBlock is as follows:
From the title screen, press MODE, then 2nd + left
Enjoy |

this game is real neat. but unfortunately i cant seem to get it to work on my calc with DCS. is this exclusively mirage? i did get it to work with wabbitemu on my ti84+SE rom with DCS but not on the calc that the rom came from....well to tell the truth the game did work but not well. it was all glitchy and the graphics were terrible, have of the logo was on the bottom and the text was shifted so some words were a line above or below. i exited right away and tried it in the emu and it worked fine so im not sure whats wrong.
edit:hmm just realized im a bit late on this topic...w/e

| Don't worry. You prolly need LCD Fix, a 84+ exclusive LCD fixer. I have no idea how it works, but it fixes the LCD driver, so games that have glitches like the one you described work properly. Gemini and Doom are a few that come to mind. |

| A bit late, but yeah, Mirage expects Asm_Flag1 to stay the same when programs are executed. Methinks this needs to be documented, but you seem to have dealt with it just fine. |

Along with the asm-flag1 thing, I was wondering if it's possible to actually make MirageOS crash if they are set all wrong, or if it's just a display error that happens because of either a failure to preserve the flags or an intentional effor to screw with the flags.
What's the verdict? (since I really don't feel like testing this one out)
EDIT2: Yeah, I agree that requiring asm_flag1 to be preserved should be stated. In bold.
EDIT1:

It shouldn't be exclusive for MirageOS. The topic discussion was about how to get MirageOS to stop being all buggy, but it's not just MirageOS. MirageOS was just the shell I used at the time to run the program. You can run it from the homescreen, so you don't even need a shell. (Instructions on how to do that are in the readme file)
It was designed with the modified ION header to allow execution from the homescreen. The original verison was *designed* to be run from the homescreen, so ION was never needed to begin with. I just included that little feature as a convenience for the users who like to use shells to play all their games.
EDIT3: So, what else do you think I can do for this game? Optimizations appreciated.

| I wish there were a more straightforward way to get these downloads while the system is out, but the actual file names don't carry a pattern. Until it's all worked out, I can fetch URL's for individual files upon request: Here's Fishy. |
