From the fight with Raditz to the fight with Vegeta.

The battle on the planet Namek. The last boss is of course Frieza-sama.

The OP is the fight with Frieza-sama. I liked the BGM here because it was really cool.

From there, it's a battle between the Artificial Man and Cell, but the game ends at Cell's first form. The end of the game is like a censored manga. After that, the RPG series never got a sequel, and DB became a mass-produced fighting game.

This fangame has gone out of its way to create a storyline that leads up to the subsequent cell games, and even includes elements from the film versions. Personally, I like the inclusion of the story of Goku's father, bardock.

It also contains elements of the following games.There may be others.

A wonderfully powerful work.

「天地を喰らう2・完全版/Destiny of an Emperor II complete version」
https://www.backloggd.com/games/destiny-of-an-emperor-ii/
The developers call this the complete version of "2".
I've played it a bit. It really is the "complete version".

The game system is based on "2" and is a port of the best parts of "1". The story also starts with Yellow Turban Rebellion, which is also a great thing for Yellow Turbans fans.
”蒼天已死 黄天當立 歳在甲子 天下大吉！”

The problem is that the developers are too motivated. Because of this, there are too many versions of the game and the specifications are not organized.
It's a luxury concern.
In fact, I don't know which version of the game is the most stable and enjoyable, even though I've checked the internet. lol

Probably either ver3.03 or ver4.08 if you want to play now.
ver3.03

Remake by volunteers. It is said to be easier to play than the original.

The story is still the same, but the game system of Saga2 has been adapted.

It has very little to do with this game.
The only thing they have in common is that they are related to JoJo Part 5.

https://www.backloggd.com/games/mystery-dungeon-shiren-the-wanderer--1/
The content is based on these two games with a pathetic boss as the protagonist. That's all.
However, this game has the developer's overflowing love for Jojo.
A game in which Diavolo, our boss, keeps dying. "INFINITELY".

"HE WILL NEVER EVEN ARRIVE AT THE REALITY OF 'DEATH... 'INFINITELY'... NO END IS AN END, AND THAT IS THE 'GOLD EXPERIENCE REQUIEM'."
What a pathetic Boss! Giorno is the son of the devil!!
"STAY AWAY FROM ME!!!"
