Homebrew grape, an Apple II emulator

[lemonmeister]

Hello there, it seems that the Nintendo DS scene is hard to die heh

https://github.com/LemonBoy/grape

Go grab it (no builds, compile it yourselves) and report back
You need a loader that supports the argv protocol (Woodr4/Woodrpg/whatever) as there's no file chooser menu.
For Wood* users just slap this in your /__rpg/associations.ini file (adjust the path if you didn't place grape.nds in the root)

[nib]
launcher=fat0:/grape.nds
[dsk]
launcher=fat0:/grape.nds
[po]
launcher=fat0:/grape.nds
[do]
launcher=fat0:/grape.nds

Also, place the basic rom along with the nds file, named BASIC.ROM (DL)
Press start to pause the emulation and enter the menu. When the keys are mapped to the joystick BXY are the three joystick pushbuttons, the keyboard mapping is a temporary one that should work for most games (HJKL are assigned to direction keys, A is return and B space).
Read the damn README before asking questions.
Bug reports and feature requests are welcome.

"read the damn README" Will check this out

this sounds fun but installing software to compile this myself does not. why not just release a binary?

Strange isn't it? I can't imagine working on a program for weeks or months and then deciding not to spend an extra 5 minutes to compile it so my audience can enjoy it. The lolsnes guy did this same goofy thing.

Anyway, enough of my griping, here's the attached binary:

It doesn't work no$gba.

Lolsnes has automatic builds now, so you don't have to wait for anyone to compile the source

Well good, maybe the dude in this thread will be inspired to reform his ways as well.

Its was a successful build with no errors on the latest devkitpro, but I can't vouch for the quality of the source code. It did boot fine on my DSi. Use real hardware when possible.

Well, we'll see

The "lolsnes guy" first did this goofy thing because lolSnes wasn't ready for a release yet.

You'll notice that now, it is released as a build, and there are even Git builds available (one new build every time a commit is made).

It doesn't work no$gba.

I guess this is because NO$GBA doesn't emulate a flashcard. If you really want to use an emulator, you can try the latest DeSmuME. Or just use a DS.

 

[lemonmeister]

I've released grape here to collect some feedback as I can't play every damn Apple II game, it's alpha quality after all! (A damn good alpha quality tho)
Anyway, you *need* to use it on real HW, not even Desmume can handle it properly right now.

 

[Boy12]

Nice work man!

 

[ipwndeveloper]

Holy cow, this actually runs some of my old demoes. Now if he could only add Apple ][GS support. I would be in DS homebrew heaven. Also built from the latest source, DSi Mode works!

 

[lemonmeister]

Hah, I don't think that the DS is powerful enough to emulate a GS. It even has problems with 80columns/dhires

 

[lemonmeister]

I've made a couple of fixes here and there, it's slightly faster than before (playing karateka w/o vsync is awesome) heh
The bottleneck here is the hi-res video rendering routine, I'm glad to accept pull requests if you can make it faster
Also, there are plans to support the AppleIIc hardware (did anyone say Prince of Persia ?) in the (near/far) future...
TL;DR Here's a compiled build

 

[Vague Rant]

Have you or do you plan to support file selection within the app, for those of us who don't have flash cards with argument support? Or is there an alternative method to run it like launching it through Moonshell or something?

 

[lemonmeister]

WinterMute's HBmenu provides argv support, just create a file named grape.argv with the path to the grape rom and the path to the AppleII rom you want to load.
I know it's a bit difficult to setup but writing the code for the file selector is definitely boring. Really boring.
Anyway, a good news, I've found a nice way to speed up the graphic rendering \o/

 

[Vague Rant]

Works for me, I just got Super Bunny running. It seems to be working from an emulation perspective, but is iffy in terms of registering inputs. That said, it's pretty cool to see it running on DS; nice job.

 

[lemonmeister]

The latest commit should have fixed all the problems related to input
Also, it's now fast enough to play Karateka with vsync on :3
As always, here's the build

 

[lemonmeister]

Gah, I couldn't get to sleep until I wrote a better hi-res renderer and optimize it to reach the ~60fps...
Well, the result is here

 

[Vague Rant]

I'm not sure what's changed, but now I'm having trouble with grape, even after dropping back to the version from last month. It seems to be running fine, but crashes upon opening the menu. I tried backing up my card, formatting it, and putting grape back on, but I'm still getting the same behavior. Since I'm getting the same behavior across versions, it can't be related to any code changes in grape, so I don't know what I'm doing wrong.
