So.. I’ve been testing out various CDi Titles in the recent MESS driver, and
I can only feel sorry for anybody who spent 700$ on one of these when it came
out. You can count the number of good games on one hand, and on most other
systems those would merely be considered average. The bad games, you’d need
more than just a desert to bury them. Almost every game on the system suffers
from glaring design flaws (as does the actual system), some of them so
obvious that you wonder how they were ever released. I approached the system
with an open mind, thinking that all those videos on YouTube of people
ripping into the games were just for show, they’re not, actually if anything
they’re too kind on some of these titles.

While not all the games work well enough in MESS to make a fair assessment
the majority don’t need to, overloaded with ‘multimedia’ content, poor
controls, illogical menus, no gameplay value, and deeply flawed designs are
obvious even through the bugs.

The only 3 games I actually enjoyed were the following

Hotel Mario
Despite some people hating this it is actually a solid arcade-style game, had
it actually been released as a sequel to the original Mario Bros arcade I
think it would have done rather well. The action all takes place on a
non-scrolling screen, just like the original and the whole thing plays like a
classic arcade title, even if the controls can feel a bit ’sticky’ at times.

The Apprentice
The graphics and animation on this one make you wonder why none of the other
CDi games come even close in terms of presentation, they’re stunning. The
sound / music don’t work so it’s hard to know if they match the graphics,
but at least with this game you know you’re looking at something better than
you’d see on the Genesis. It’s another simple platformer, this time a
vertically scrolling one. You must get from one end of the level to the
other, avoiding various enemies, and collecting items that will help you pass
other parts of the level. It’s not a flawless game, you notice straight away
that any enemy which even leaves the screen by 1 pixel becomes inactive, and
the control system only allows you to fire when you’re on the ground. These
problems don’t however stop it being by far the best thing to have been
released on the CDi and make you wonder what could have been done with the
system if more good developers had been involved.

Dimos Quest
This one is from the same team as The Apprentice, and shares a similar
graphical style. It’s not as polished as the former, and the ingame sprites
are tiny so it doesn’t look quite as good. The game is puzzle-based in it’s
nature. Each level consists of a number of pieces of candy, you have to
collect them all and reach the exit without being killed. The levels are full
of hazards and obstacles, and each one must be dealt with in an appropriate
way. There are a large number of special items and the later levels are of a
large enough scale to present a significant challenge to even a skilled
player. My only gripe is that the controls feel very laggy and you often
overshoot the square you want, sometimes leading to your death; I don’t know
if this is an emulation bug or a problem with the original, bad controls seem
to be a theme mentioned even on the YouTube CDi videos on a frequent basis.

Thankfully these 3 are playable right now in the MESS driver. I’ve also
compiled a Tiny MAME build which incorporates the MESS code, below.

A couple of other games look interesting but simply don’t work. MegaMaze
looks like it could be a good puzzle game, sliding marbles around a maze.

As for the bad…

The Zelda games are an abomination, seriously, they have no redeeming
features at all, neither works well enough in MESS at the moment to make any
great amount of progress, but the game mechanics are so bad you simply don’t
want to anyway. The video (cartoon/fmv) based games are mostly pointless,
especially the Wacky Golf game, which isn’t even funny the first time you
see the clips, and most games are laden with FMV where FMV doesn’t need to
go.

The ‘board game remake’ titles (mostly from ‘CAPDisc’) just serve to
annoy, by being slow paced, ugly and clumsy in their implementation.
As for the ‘Arcade Classics’, ‘Family Games’, and ‘Golden Oldies’
packs, each and every game feels like a poor joke; for Family Games 2 you
can almost sense that the programmers knew it was awful, so simply made it
into a joke with their parodies (Mortal Pong??). There is no consistency in
the games aside from them being consistently bad, each one of the arcade
classics is prentend in a completely different way. Galaxian has no
decoration, Galaga has so much decoration it looks like the game is afraid to
use more than 1/4 of the screen, and MS. Pacman has been tarted up, has had a
(flawed) 2 player mode added, but the enemies have been dumbed down so much it
’s not even worth playing and those are the official ports!. The unofficial
ones found in ‘Golden Oldies’ are even worse, BlockBuster is Arkanoid, but
done so wrong it’s not even funny. The initial jingle you get on starting a
game is a direct rip-off of the official Arkanoid jingle but a bit more ’
spacey’ (I’m surprised they weren’t sued) but the rest of the sound
effects just sound completely out of place, and when you miss the ball they
decided to add a long winded animation where your paddle turns into a skull
and falls apart whilst playing a generic Aaaaargh sample. You’ve also got a
Defender remake, a Centipede remake, and a Space Invaders remake, none worth
your time. There were better classic ports and remakes on the 8-bit systems,
these are just embarrassing. For the most part these compilations work well
in the driver, althouh the official Namco one has issues, and some of the
minigames in the Family Games series don’t run properly.

Micro Machines has a port, but it’s a disaster, the framerate is somewhere
around 20fps, they’ve added some bad FMV sequences, and it has no in-game
sound only music, those aren’t emulation issues either, it’s exactly like
that on the original hardware.

Video Speedway seems like it has potential, until you reach the actual game.
The menus are well presented, but the actual game is a very, very poor clone
of the Genesis version of Super Monaco GP, your car sounds like it has a
broken lawnmower for an engine, and your tyres screech like a screaming
teenage girl, the graphics are bland and the game near unplayable.

Honestly, the CDi is terrible, most systems have their share of bad games,
but the bad games on CDi make up the majority of the titles, you have to play
some of them simply to understand how bad they are but once you’ve played
them once, you’ll never want to go back and play them again; at least not
unless you’re suffering from a severe case of memory loss and forgot how bad
they were.

Good to see emulation of the system improving… Now.. to wash my eyes out..

TinyCDI 28/10/09

This is a ‘Tiny’ MAME build containing the CDi code from MESS as it is on
28th October 2009
using a fixed gamelist like MAME.

Most games will lockup or crash at some point due to imperfectons in the
emulation, a couple
of them do however play well.

Hotel Mario, The Apprentice (no sound), Dimos Quest, Alien Gate, Jokers Wild,
Tetris and a
number of others seem to be perfectly playable.

Digital Video titles won’t work because MESS doesn’t emulate the MPEG card.

For most games only one revision has been added for testing purposes, while
multiple revisions
exist in the TOSEC dats. Non-games haven’t been added at all for now.

I haven’t marked games as working / not working because most of them haven’
t been tested far
enough to make a good judgement on that, the main guarantee this tiny build
gives however
is that if your CHDs match the expected ones, you’re getting the same
results as everybody
else; something which is hard to know in MESS which lacks any kind of fixed
set list.

I (Haze) take no credit for the work here, I’ve just been converting images
and testing them.
The driver is mostly by ‘Just Desserts / Harmony’ and progress can be
followed at the MESS
forums.

The CHDs used by this should be compatible with future versions of MESS.

The package is provided as a ‘tiny’ package which extracts over a full MAME
source.

Have fun, I don’t personally want any bug reports for this, you’re on your
own ;-)
