Newest PAC MAN release (9/22) looks under-sized and shows install error

Hey everyone. It's been a while, but I'm back in the custom ROM game. Took me a while to pick one for my Canadian i337 S4, but settled on the PacMan rom.

In regards to the released rom here:
s.basketbuild (dot) com/devs/pacman/jfltecan/Official

The previously release is about 236MB ( pac_jfltecan-lp-mr1-Official-20150722.zip )
The newest release is only about 66MB and produced an error when trying to install ( pac_jfltecan-lp-mr1-Official-20150919.zip )

I ended up installing 07/22 without a problem. Can anyone verify what this 9/19 release is all about?

Also, would updating a rom in this situation cause me to start with a clean install? Or do they just patch the old data when installing?

Best back cover, that looks in aluminium

ANy recommendation for back covers that look like aluminium (or in aluminium, why not) preferably without the samsung logo or galaxy logo (preferably NO logo)

Thank you!!

Mi 4i - one more reason why mi 4i front camera looks more capable then back

Mi 4i front camera can record video in 1080p with 50 frame per second
While back camera can record video in 1080p with 25 frame per second
