The arcade-congo from opengateware

arcade-congo's Introduction

Sega Congo Bongo Compatible Gateware IP Core

This Implementation of a compatible Congo Bongo/Tip Top arcade hardware in HDL is the work of Dar.

Overview

Congo Bongo is an isometric platform game and is Sega's take on Nintendo's legendary "Donkey Kong". The player takes on the role of a red-nosed safari explorer by the name of Safari Sam, who tries to catch a gorilla named Bongo.

The game consists of four different scenes. Each is timed by a bonus counter in the upper left corner of the screen. As time passes, the bonus decreases. If the bonus counter reaches zero, a player life is lost.

arcade-congo's Issues

Tate mode (Feature Request)

Firstly, thanks so much for all the work you've done to bring historical games into the modern day.

Would it be possible to add a rotate option in the menu so I can play in TATE when I'm docked?

Horizontal/Vertical Scanlines Reversed?

Version (or build number)

0.1.1

Steps to reproduce

Given that the screen is, I think, rotated for this core, you may consider this a non issue. However, the horizontal and vertical scanline settings actually generate the opposite, from the players perspective. It's possible that you consider this technically correct, but I thought it worth mentioning.

Expected Behavior

I think most players would expect these settings to produce the intuitive display changes in their already rotated device.

Actual Behavior

Horizontal produces vertical scanlines and vice versa.
