Official TI-Boy SE Beta Thread

It has a proper ROM. I took the ROM from my calc using the software included.

In the Axe bugs thread, someone mentionned that some versions of WabbitEmu like to insert BootFree into dumped ROMs, so even if you dump a ROM from a real calc, unless you got the latest version of WabbitEmu I believe, you could still end up with a Bootfree ROM.

By the way, TI-Boy SE Beta 0.2.04 is now up on ticalc.org! http://www.ticalc.org/archives/files/fileinfo/419/41990.html

Took me long enough...

[DJ Omnimaga]

Glad to hear. Can't wait to see the color calc version out there too eventually

I recently downloaded Beta 0.2.04, and every game I convert shakes like crazy, and is vey unplayable. Do you know why this is happening? It's really sad

[Runer112]

By "shakes like crazy," do you mean like this?



The Game Boy has a screen size of 160x144, while the calculator has a screen size of 96x64. To make the former come close to fitting on the latter, it is shrunk by 50% in both dimensions to 80x72, squishing every square of four pixels into a single pixel. I believe the emulator achieves this by quickly cycling through all four source pixels to display for each output pixel. One very important thing this does is retain some level of text readability. Compare this:



To what it would look like if it just statically selected one out of every square of four pixels:



Some characters look pretty good, but others are missing parts and are completely unrecognizable. This made the text in basically every game unreadable, which was a huge problem. Non-text graphics also suffer a lot when downsized statically:



I can barely tell that the figure on the right is Red/Ash, and I absolutely can't read any of the version text.

If you want a somewhat clearer image, the only option is to zoom in with the + key (you can also zoom out with the - key), although you will of course be cutting of parts of the screen in doing so. Zoom levels under 100% will still have the "flickering" effect, but should be less pronounced at higher zoom levels. You can zoom all the way into 100% for the original, crisp graphics, but your viewing area will be severely limited if you do so. You can also enable grayscale by pressing Graph/F5, but be warned that it doesn't look too great when zoomed out; I'd just recommend sticking to the black and white mode, then. For more zoom/graphics controls, refer to the readme.

If this wasn't the shaking you were talking about... well then I'm not sure what to tell you, and I wasted a lot of time making this post.

Well it's an interesting post, I didn't know about this yet. Your time definitely didn't go to waste

[DJ Omnimaga]

Yeah when zooming it usually works fairly well, especially considering you can center the camera on a sprite of your choice. Else, if full screen, it still doesn't look too bad due to the anti-aliasing mentioned above, although due to speed constraints the grayscale does flicker, so that is why it's shaking.

[Addison Bean]

Thanks, the zooming thing helped!

Totally dumb question- does it work with the ti-89 titanium? If it isn't compatible, would you consider making a similar emulator for the ti-89? I thought that this emulator was very easy to use, and I would like one for the ti-89

[Iambian]

Holy necropost, Batman!

Erh. Anyway...

(1) This does not work for the TI-89.
(2) I can't answer that, but I can definitely say that TI-Boy is written in z80 assembler and is designed to run on the TI-83/84 Plus SE. The TI-89 has a completely different architecture (68K) which makes what is currently written incompatible on nearly every possible level.

After a quick Google search, this looks like that would solve your needs. Try it out and tell us if it helped.

Hello,and I have found a serious bug in the emulator.
It seems that if you run the emulator, go back to the homescreen, and then enter a REALLLLLY long expression,
The calculator will go blank and then reset the RAM.
idk why this happens, though.
Rom Version:2.55MP
Ti Boy Version:0.2.04
Calculator Model:A Ti84 Plus

I would recommend trying to replicate with the latest release, and then opening an issue on the repository if you can: https://github.com/calc84maniac/tiboyse/releases
