This is what receiving a GRP looks like on the receiving system. (each text character is a pixel worth of data)

Generally I'll only make one post but since the system is in Local Wireless mode when I take the screenshot, I cannot use miiverse properly. Here is that key for SENDFILE again KEY:EXEQW33J

wow

It might go faster if you don't print the text on screen since scrolling is slow.

The systems are actually limited to roughly 30 successful packets per second. Running any faster would just cause the system to overload and would crash the program.

Update: 43SPEEN3 (also best key i've ever seen) v0.60 Added DAT file support (1 Dimensional only) Added proper buffer check(Prevents Crashing) User Friendly stuff

OH and you can now send SENDFILE to a system without it. For more details, see https://smilebasicsource.com/page?pid=342
