You only need to arm7 patch those games that don't work on 1.18. This 1.19 is fake. it's just a poorly hacked up version of YSMenu. I wouldn't trust it on my R4.

Here's a simple HOW-TO for arm7 patching: HOWTO: Patch arm7.bin. .

I can also provide info for installing YSMenu for R4, but you might as well just patch the arm7s since this fake 1.19 release will probably piss Yasu (Creator of YSMenu) off to the point that he will stop development. And you'll just be right back to square-1 having to arm7 patch games on a, for the most part, dead card.
