* Add detail about additional RAM disk slots Also corrects usernames, some grammar/clarity changes, and adds note about the Windows requirement * Bullet adjustments and clarify accessing DS Classic Menu on DSi I changed the PictoChat and flashcard instructions to individual sentences, because in my opinion the single bullet for a step looked bad. * Add some details to the app installation question This does technically make it repeat itself a bit, but the invalid title section may only be viewed *after* they've hit the issue. Also corrects capitalization per CONTRIBUTING.md * Add details on other ways of connecting Also removes the Windows hotspot link * Link to online checksum calculator * Punctuation and more accurate NWFCUSBC info Also, the last commit added the AltWFC online player list, but I believe I forgot to mention that * Add information to top

In order for GBARunner2 to load titles, a dump of the GBA BIOS is required. Newer builds of GBARunner2 (which come with the latest release of TWiLight Menu++) have [Normatt's Open Source BIOS](https://github.com/Normmatt/gba_bios) built-in. However, because it is not an exact copy, using a dump of the official BIOS increases compatibility. You can dump an official GBA BIOS with one of the following methods.

|
### Dumping Guides
|
|
|
|
- [Wii (not family edition)/GameCube + link cable dumper](https://github.com/FIX94/gba-link-cable-dumper)
|
|
- [3DS using most Virtual Console titles](https://glazedbelmont.github.io/gbabiosdump/#virtual-console-title-from-a-3ds) (Can't be GBA or non-Nintendo (Game Gear) Virtual Console Titles)
|
|
- [GBA or DS Phat/Lite with a GBA flashcart](https://glazedbelmont.github.io/gbabiosdump/#gameboy-advance-sp-micro-ds-ds-lite)
|
|
|
|
After dumping the BIOS, it must be renamed to `bios.bin` and then should be placed in `sd:/`, `sd:/gba/`, or `sd:/_gba/` for GBARunner2 to read it.
|
|
|
|
You can verify that your BIOS is a proper dump by comparing it with the following checksums:
|
|
|
|
**CRC32:** `81977335`
|
|
|
|
**MD5:** `a860e8c0b6d573d191e4ec7db1b1e4f6`
|
|
|
|
**SHA1:** `300c20df6731a33952ded8c436f7f186d25d3492`
|
|
|
|
**SHA256:** `fd2547724b505f487e6dcb29ec2ecff3af35a841a77ab2e85fd87350abd36570`
|
|
|
|
If you don't know how to obtain a file checksum, you can use an [online checksum calculator](https://emn178.github.io/online-tools/crc32_checksum.html).
