Nah, I would rather show respect by letting you finish all the stages from stage 4 to stage 8 so that you have a complete map set. Sometimes its better if a person has his/her own personal collection, I'm not into hogging the Streets of Rage collection just because I finished the SMS version games. If you're lucky to finish Streets of Rage 2 (SOR2), you can start on Streets of Rage 3. This isn't a race or competition, so you can take your time. I myself am in no hurry to finish Streets of Rage 1, I'm busy trying to finish some games in the SNES recreation. I gave the SOR2 a playthrough and its way better than the SMS version. I can't wait to see it fully done.
Finally if you take a look at my SOR1 map you will see a blue line at the start indicating I've added the bit where you scroll back when using the special police car attack which I have no shown in the SMS game.
