Since I found out about a "press simultaneous button" crash glitch in the main menu in Legacy of Goku I, I thought I might try it in this game. I didn't find anything except: This is only a graphical bug that happens when pressing Start+B or A+B at the file select. But it suggests the game may have other menus vulnerable to this.. - A similar graphical glitch like above happens when selecting Credits from ingame pause menu (press A+B). - I have found that if you awake from sleep mode then the game continues but may give a lag frame every half second as opposed to no lag frames at all. This happens only sometimes. This keeps going even through pause screens. I don't understand why this happens... - If you highlight Credits in the ingame pause menu and press (up+A), the game seems to attempt to show the credits but immediately cancels out. Then, none of the menu options is highlighted. You can press down once, or up 5 times to highlight something again. Nothing seems to happen when trying to select out of bounds option. I ended up being unable to unpause the game when testing with that bug. Also, pressing left or right when nothing is highlighted didn't give the "buuh" sound... Not sure how that happened to me but nothing special seemed to happen then either.

Things I know of: - You don't always want to power up, as sometimes when you do, you move slower. Even if the game says to power up, you often want to ignore it. - You can kill Cell with Goku's bomb attack if you charge it up with multiple beans.

I've been working on a WIP Testrun of this game with one of my friends and finally decided to upload our WIP. Link to video Be sure the read the description of the video, it has various comments/notes and the VBM. Also if anyone could help me with finding the coordinates and RNG addresses it would help immensely. Thanks :)

I will watch your video. http://dehacked.2y.net/microstorage.php/info/1009141117/DBZ2.vbm VBA19-23 This is a WIP I made in 2010 but I didn't get very far. I think there are some possible improvements e.g. if Trunks didn't shoot before flying to the next map to chase Gohan, you might save a few frames. And I ran right of the stump, you ran left of it (which I think may be slower). But those are only nitpicks. I'm glad you made a long WIP. I only now see you mentioned "Testrun".

Comparing your WIP to ours, we were 30 frames slower so far. The ki blast before flying didn't waste any time but I made a quick TAS fixing the flight pad and your suggestion about the tree stump and saved 3/13 frames respectively. I added that to the notable improvements. Thanks :)

I'd be interested in collaborating if you're still working on the run. I just really suck at reverse engineering RNG, unfortunately, and it's the main thing that the tas needs to destroy the game. It's definitely worth it to get max strength boosts and manipulate starting stats (as those are random except for Gohan's stats; future Trunks stats have no effect on him later in the game from the tutorial areas). Also there's a European version or something that has objectively better sprites (uses the same as JP version) Quick Edit: Thought I'd mention this but if you press start on the first frame of gameplay in the tutorial area right before Gohan's text boxes appear you can softlock or crash the game by scrolling through menus. Also you get to see weird stats on characters you don't have yet.

I'm down for any help I can get in case I run out of motivation again. idk how TASers do it lol. I recently picked this back up after the RTA community reached out to me. I finished up to the dinosaur eggs part but I'm not happy with the 3rd one. Here's the 2 short WIPs of those sections which I forgot to share on here. Link to video Link to video EDIT: I believe I found addresses related to RNG but I also don't have any idea on how to reverse engineer them. 03003890-03003897 They seem to change based on various actions including inputs, and other things like when the screen shakes. Pausing and when an enemy is really close to you they change every frame. I forgot to respond to this part before but I chose the US version simply because it was what I had. I haven't bothered looking to see if there are any differences between the PAL/JP version but I've been told the US version is the slowest lol.

A small update since it's been a while. Amphorce has started helping me again with this TAS and we've made a decent amount of progress. Also to point out with this particular strat we plan on skipping Gohan's charge attack to stay as Trunk for his faster Super Saiyan movement. It doesn't take very long to get but we have no idea whether it will matter and we can't test until WAY later in the run. I mention this because the RTA gets it. EDIT: Finished up the grinding. I deleted the stuff about strats from the post since the next day I immediately realized one was way better so it didn't matter anymore. Link to video

We knew about that and may or may not have used it already ;) Also for an update we literally haven't touched this in 2 months because of more grinding that's even worse because Piccolo does like no damage. It was only the other day we decided we we're gonna try to pick it up. It still would be super useful to understand RNG cause he's already getting bad level ups (no strength)

Link to video The bug doesn't seem to work in the Japanese version because of how it handles errors. It will bring up one of its error screens instead of glitching up. Link to video

this game is that much bigger than the first one?
I want all good TAS inside TASvideos, it's my motto. TAS i'm interested: Megaman series, specially the RPGs! Where is the mmbn1 all chips TAS we deserve? Where is the Command Mission TAS? i'm slowly moving away from TASing fighting games for speed, maybe it's time to start finding some entertainment value in TASing.
