BUt not everyone can pay something online. I remember having troubles to buy Minecratbefore having my own credit card...

Well, you can also buy eShop cards in stores, but those are usually at minimum $20 if I remember correctly.

Oh I was asking because I didn't update my copy in a long while.

I'm not sure if DSiWare titles even support updates. But yeah, pretty sure 2.2 is the only version release in North America. (2.4 for PAL regions)

Mega necropost here, but I've finally finished up that Steins;Gate 8-bit demo! Once again, I'll give the disclaimer that since this is a sequel to the Steins;Gate anime/visual novel, it might not make sense unless you've watched/played it (and I recommend you do so, it's fantastic!)

The game this is based on is meant to emulate the environment of old 8-bit computers in an old-school text adventure, which includes the low color depth and legacy sound hardware. The original game allowed selection of 6 different computers to emulate, each with slightly different graphics and music arrangements, but this port I'm simply basing on the Petit Computer environment (with most of my music arrangements created using 3 MIDI-style channels and 3 square wave or white noise channels).

This demo contains the entire first segment of the game up until the opening credits, which I believe is the length of the free demo of the PC version. This includes 9 background music tracks (out of 18 total) and 16 different CG images, as well as 3 different endings.

Here are some tips when entering commands in the game, because it can be slightly confusing. There are usually three rules that valid commands follow:
1) If you want to move in a direction, simply type the direction. (left, right, front, back, up, down, etc.)
2) If you want to perform an action, simply type the action. (look, talk, eat, etc.)
3) If you want to perform an action on a certain object, type the action then the object. (look poster, kick can, etc.)

If all else fails, just look up a walkthrough online.

The QR codes are contained in the spoiler below:

I think this was a smart move. It comes out on the same day as Pokemon X & Y, so it will probably explode in sales. Strange how apparently the 2DS isn't being released in Japan, though... I guess there are so many people with 3DS's there already that they just don't care?

Just be sure to backup often, because I heard a lot about people losing their progress due to corrupted SD card or something.

Actually, in my case it was because I didn't move my DSiWare titles to the SD card (from system memory) when doing a system transfer to my new 3DS XL. Still a good idea to backup, though.

Just 160x240 mode and/or scrolling (for now, anyway)

TilEm does support 160x240 mode, yes.  Most of the documented LCD controller features are supported at this point; some of the undocumented features still need to be tested.

As far as sprite orientations are concerned: in most cases, you should be able to store the sprite in whatever orientation you like, and flip/rotate it by switching the output mode as desired.  As for the case of wrapping around that calc84maniac mentions: that's one of the undocumented features I still need to explore.

Actually, for the wrapping around, I'm referring to having a window of (y1,y1+height-1) and (0,319). If you draw vertically, you'll wrap around after 319 (not undocumented at all). However, from what I saw on the SVN, you may not be clipping LCD coordinates to 8-bits or 9-bits upon write. Any bits listed as 0 in the data sheet is forced to 0 (i.e. writes are ignored). This should be useful for some code optimizations, I think.

If you want to pause for a very small, precise amount of time, I would suggest something like the following:

Code: [Select]

For(N)
End
This block of code just executes an empty loop N times, and it will do so at about 13 cycles per iteration.

Does the push bc \ pop bc get auto-optimized or something?
