DS85 R3 is a TI-85 Emulator for Nintendo DS. Original version by Milan Pikula. It requires a TI-85 rom to run.

Installation

1. Download and extract file
2. DLDI patch .nds file and copy it to the root directory of the card
3. Copy the ti85.rom to the root of your card(no subfolder) (This ROM cant be found with this app. Read below "To obtain a TI-85 rom")
4. If you want additional features, you may want to copy ti85.sna to the root as well.

It includes some ASM Games. After it has loaded, press Custom -> F1 to get to the gamemenu.

User guide

To obtain a TI-85 rom: Get a TI-85 calculator. Make or Get linking cable (serial or parallel should work)

Download a rom dumper. Virtual TI (Windows) and TiLP (crossplatform) can both do this.

Follow instructions provided with rom dumper.(Optional) Use 'fixrom'. A few people have complained of corrupted ROM files, this tool will fix your problems. See the included README.fixrom

GUI buttons

SAVE: Save the current state to 'ti85.sna' on your CF/SD card

LOAD: Load the current state from 'ti85.sna' on your CF/SD card

RESET: Tap this to do a full reset of the calculator in case it crashes.

SIZE: Tap this to toggle scaling from proportional to stretched

REAL/FULL/freal: Tap this to switch between the emulation modes

REAL -- attempt to emulate at actual speed (This isn't quite perfect yet however)

FULL -- emulate as fast as possible

freal -- emulate at actual speed, unless doing processing, then run at full speed

SKIP/ALL: Tap this to toggle between skipping frames and rendering them all. It is slightly faster when skipping frames, useful for graphing/calculation, but games will probably want ALL.

SEND -- Read section below

Sending Files to the TI-85

Method 1: Standard link emulation

This is more cumbersome, and you have to worry about running out of RAM, but should be more compatible. Also, this is required for apps with external levels.

1. From the home screen, click [2nd] [LINK] [F2]
2. The screen says 'Waiting' and the busy indicator in top-right is spinning
3. Tap 'SEND' on the touchscreen
4. Use D-PAD to scroll through the files, and press A to send a file
5. After it returns to the GUI, you can either:

A. Send another file (go to step 3)

B. Stop sending files (tap ON key a few times to stop transmitting)

Method 2: MagicLoad(TM)

This is very nice when it works. It's similar to the 'archive' on other TI models, in that it will load a game from your SD/CF card, run it, then save it back when it's done.

1. Make sure 'LOAD.85S' is install on your calculator, along with Usgard 1.5 (These are both pre-installed if you use the included save-state)
2. From the home screen, click [CUST] [F1]
3. Use Arrows to select 'load' on the list of apps (it may be the only one)
4. Use ENTER or A to launch it
5. A file list will appear on the bottom screen
6. Use the D-PAD to scroll through the files, and press A to launch one
