I have bought and read every single pokemon manga since they started editing them in spanish in 2016. They've published all the way from Blue/Red to Emerald, and then they published Black and White and XY. After that they started publishing Diamond and Pearl but just the half, and now in summer they are going to continue publishing it alongside with Omega Ruby Alpha Sapphire, but I don't know if I should read ORAS if I havent read DP, Platinum and HGSS yet.
