First off, only play this in Jap if you know how to read Jap. Reason being is that you will be using Item cards. If you can't read Jap, just stick with the English Patch.

Speaking of the English Patch, there is ONLY ONE WORKING ENGLISH PATCH. Type DBZ assault of the saiyans red comet in Google. It HAS to be the Red Comet Patch.

Now for the actual Routing of the game. Also I'm going to link you to a walkthrough of the game that shows you maps. So make sure to check the map and remember it. Also the Website will tell you how to play. Also check out the Mini-games.

Keep characters close together for them to be in the same battle. Also Best M Group means best Monster Group with most BP gaining.

Stage 1: Vs. Raditz. Map: http://shrines.rpgclassics.com/nes/dbz1/walkthrough1.shtml Best M Group: Onionx1 Cucumberx3 #1: There is a Healing House next to you, Grind some BP until you feel save to go to Bulma's. #2: You have to go to Bulma's to get the Radar. You're not aloud to reach Raditz without it. #3: Grind here until about 700 or 800 BP for Both Characters. #4: Go to the Item Mini-game above you, Try to get some Chi-Chi, Escape, and Healing Cards. Keep doing this until you Max Items. #5: Now go all the way right of the Map until you reach the Healing House next to the Space Pod. #6: Grind BP until 1000 BP for Both Characters. #7: Go through the Space Pod fights and Beat Raditz. 300HP.

Goku Vs. King Kai

Stage 6: Vs. Vegeta Map: http://shrines.rpgclassics.com/nes/dbz1/walkthrough6.shtml #1: Go Beat Saibaiman x6. #2: Heal at incoming Healing House. #3: Beat Nappa and Hope you have Goku. 1800HP If not, only use one Grampa Card if you have multiples. #4: Heal at incoming Healing House. #5: Use all your Cards and Gramp Cards to Beat Vegeta. 1200HP. If he goes Ape, he gets an extra 150 HP. Which can go back down. Just Have Krillin use Distructo Disk on him.

There you go. Good luck, you're going to need it.

Also one more thing. It seems that after your characters get over a certain amount of BP the Strongest Enemy Groups that give you the most BP seem to always run away. If anyone can find a way to encounter them more and make them stop running away, that can save a lot of time.

Anyway thanks for reading all this.
