I need a little push to start the graphic part that worries me a bit.

The idea is doing a RPG for TI-83+ with 8x8 tiles. You can combine some to make houses or higher trees for example.

But how good the graphics can get with this size? I would like some game examples and/or sprite sheets. I need sprites to study a bit.
I am curious and undecided between B/W and 4 lvl grayscale. 8 lvl grayscale is out of my reach right now.

How do you make graphics? Try on calculator or computer? And just changes pixels around until get a good effect? I tried to do parentheses for a font set and I never reached one that seem nice. And it was 8x8 not 4x3. X_X

I start to want to try Game boy pocket developing. xD

Yeah I would agree with SolusIpse about DS dev. Since DS came out GB dev declined in popularity. The same will most likely happen to the Nintendo DS and PSP when Nintendo and Sony releases new handleds that are more powerful, though, but it will take a few more years at least.

As for tiles creation I generally do them using Paint or Photofiltre Studio. Paint Shop Pro and GIMP can also work. Photoshop is more oriented toward photo editing than pixel art, though. Paint.NET can also do a nice job. Just google it.

I hope you aren't quitting calc developpement, though. (Eventually, Omnimaga might be forced to expand toward ROM hacking and developpment on handled and more PC games, simply because the TI community isn't in a very good state, despite being more active in the past 6 months, and a lot of people are interested toward DS/PSP developpement, meaning they might move on, so we might need something else to back us up to keep our former TI users. However, I do not plan myself to get into console/handled programming, simply because for me it's too complicated. I might do some ROM hacking, though, with ROMs that got editors that allows you to edit the game without programming knowledge, like Lunar Magic for Super Mario World. Besides that, it would most likely be PC RPG making)

EDIT: Aren't all Lost LEgends tiles alerady done, though (if you are actually talking about Lost Legends)?

I will do games for TI calculators. Just the screen of GB has so much resolution that more appealing things could be done (greater world maps) Also GB because it is a z80 and I have looked in a dissembler and it is pretty familiar to me.

I was not thinking in action RPG. But I am creating something original so never know what is going to be.
I played Golden Sun. Great game, with puzzles and epic journey. The battles animations were really legendary.
Maybe I can pull some good effects when I gain experience in asm. Like zooming and rotation a sword.

True, Lost Legends has all design done. It is just programming and put everything together. But its tiles are 16x16 by the way.
I need tiles for a possible next RPG. I am brainstorming it in a paper.

My complaint about Paint is that is hard to know if the sprites continue to be 8x8. But thinking on it discovered that making a chess like table with 2 colours can solve this...
Trying Paint.NET... The grid I need is there. But I haven't experimented enough to discover how to move a small 8x8 without it being expanded, it only lets in bigger selections...

Well, now it would be nice catching games with 8x8 tiles... Or sprite sheets around. I will see Robot War then.

I think he's talking about the very limited zoom. In most softwares you can zoom enough to make a 8x8 sprite fit half of the screen but in paint the max zoom is 8x (altough I heard rumors that there was a way to zoom 10x). I personally didn't mind this much back when I used paint because I worked on 800x600 resolution (15 inch monitor), but for someone working on a higher resolution it might be a small issue.

My other gripe about paint is that the mouse cursor position is a bit off/misleading. For example I'll point the pen to a pixel but when I click, it will colour the pixel above instead. This can get a bit annoying when doing small pixel art. But paint is still my second favourite when it comes to pixel art. I only use Photofiltre more now because it has layers and tools to replace a color in particular in a picture or turn sprites monochrom with checkered pattern, which can be very handy when making 3 level grayscale tiles
