The BETTERSPORE grox & cell parts were the first mod I tried for spore. that's definitely the BETTERSPORE parts icon in this mod. Davo, I don't think it's exactly the tab from BETTERSPORE, the row/column count is different so he might have recreated it himself. In my opinion, he DEFINITELY used the Betterspore grox parts as a resource as a minimum. This Mod also gives you the grox background and voices in the space stage(I just tested it to double check). The only other mod I found that did that was on sporebase and it was one that only replaced the knight archtype with grox archtype. While there may be more, I didn't find them when I searched.
The Voice/Background/archtype mod I referenced can be found here:http://www.sporebase.com/forum/index.ph ... topic=4838
My conclusion: Hacker Definitely used BETTERSPORE grox parts to make his mod, Whether he created his own and took parts/icons from this, or just took it outright and changed a few things is unknown. For the background and voices, i suspect he used the above mod as a reference since I had the voice and background playing as a wanderer instead of a knight. So this part may actually be considered a new contribution.
To Hacker80: I agree with what everyone else has said about giving credit on your mods. there is no way you just happened to think up the EXACT same Icon as BETTERSPORE. I tend to assume the best in people until proven otherwise, but you need to credit where you got the pieces of your mod from. based on my search, you may have some original stuff in there with the voice and background. but credit where credit is due. if someone took this and made some small changes/add-ons to it, wouldn't you want credit for creating what they started with?
