The Mojon Twins released their stunning NES homebrew Lala The Magical! Go and get the free ROM to play this great platformer.

Story:

In the ancient ruins (province of Badajoz) lives Lala with her teacher. She is learning magic but still has a long way to go.

“Tell me about the Sky Palace” – asks Lala, and her teacher tells her again about the three Power Gems hidden inside. “I’d love to see them”, but Lala’s teacher would say no… “It’s too dangerous, and powerful magic is required to traverse the palace”.

But now the teacher has left for a few days and Lala is bored… “His Magic Wand should provide a power that’s strong enough to be able to cope with the perils hidden inside the Sky Palace. Problem is, the Wand is locked in a special vault, and the lock is also magical!” Not only she needs to find the key, but become stronger collecting eight magic potions.

Let’s get busy! Help Lala get the Wand and travel to the Sky Palace to find the three Power Gems! Just because she’s bored!

Dragon Leap is an older NES homebrew game by 64KB Games, which totally slipped under our radar, but better late than never? If you are into platform/puzzle games, this might be a pretty nice game to check.

After a nice dinner of succulent cattle and one very angry farmer, the little green dragon decided to take a walk while his food settled. So the dragon decided to take a walk though the red mountains. Then the rock crumbled beneath the dragon’s feet as it fell into a strange cave with faces carved into all the walls. Can the little green dragon find it’s way out of 464 rooms spread across 8 strange mazes?

MintaBOOM by za909 is a new, work-in-progress music player, which aims to make it possible to play sample-based music in games without having to completely suspend gameplay. The additional cost of an IRQ source in a cartridge has also been considered, and as a result, no complicated mapper hardware is needed to make use of the music player, as it runs using the DMC channel for its timing!
