SIG X68000 / Re: MIDI and 8MB card
Last post by Cyothevile - January 22, 2021, 04:30:48 AM
Hi just want to say I placed aje_fr board inside my XVI and it works very well. It is expensive but he also use expensive chips and he worked very hard so this is a fair price.

It's a very excellent economic solution as you can play all the games from hard drive due to high RAM and have Midi... So we don't have to attack each other on Yahoo Japan auction anymore. So if anyone here is thinking they shouldn't buy it... I recommend you get it quickly.
Console Mods / Re: N64 RCP overclock tearing ...

So the assortment of clocks I ordered arrived today.

I could push X1 up to 25.0mHz but no higher as the console wouldn't boot.
X2 wouldn't boot at 20.0mHz and that was the next up from 17.7mHz that I had.

So now within the realm of a 1.5x speed I checked the timing for comparison and found it wildly out, with a 26 second video I took capturing 31.85 seconds of "game time" which suggests that things aren't quite linear. I dropped a switch on the CPU to give some control between 1x and 1.5x and didn't feel that the 1x provided better performance. Interestingly at 1x speed the "game speed" as demonstrated by the clock in PD was ever so slightly slower than actual time with a 26 second video capturing 20.55 seconds of game time.

Frustratingly I still can't get the Everdrive to work, and even then it wouldn't be a good measure of performance improvement as both clocks have been changed so this is left sitting in the realm of non-qualitative measurement, ie. videos and guesswork.



And you bet my pet bird "Fluffy" helped out, and I think that's why there are green dots in the HDMI feed - I think he pulled on the ribbon a bit too much.


So...drawing to the end of a long road for me, and I really don't feel that I've found a "win" at this stage. I'm sure I could get a 20% boost without corrupted video if I could use the Everdrive and adjust the gameplay speed of Perfect Dark or Goldeneye directly, but the Everdrive just won't boot.

I think for the next part of this experiment I'll see about looking at the different X2 clocks and at what point the video tears begin to happen - I might be able to squeak out a little performance that way, and a little is better than nothing.

So I recently wondered if the video would work were the chip set to the correct clockrate. Finding myself short on the necessary bits to do this correctly I opted to simply jumper from one N64 to the other.

Suffice to say that it didn't work. Could have been my Michael Mouse setup, difficult place to drop a wire (someone put an UltraHDMI cable over the chip! How rule!) or simply just a stupid idea.

Image Fight use a protection almost invisible on both disks :

Sector 08 of track 76 of each disk is empty, but has errors informations that are checked by the protection routine.

A-Jax use a copy protection on the system disk :

And on Data Disk 2 :

The protection is very probably checked in the later levels.....

While true, @kamiboy, I don't think staying oldschool means staying phallic.  I'm not the same person I was when the forum launched (holy shit) 18 years ago.  I still love my fun but I'm also aware of how things like this reflect on me, the forum, and all of us. 

Tell me you'll still love me when I mess with your throbbing member.  ;)

I like the silly titles we are already endowed with. Forums like this are a holdout relic from the early wild west frontier version of the web, before everything was sanitized into a professional easy to commercialize sleek fenced in gardens of mega corporations, designed by committee according to the latest market researched web standards. People who want to play in the kitty pool can go to the facebook interest groups with orders of magnitude more members and activity.

I rather we keep the ironically childish member titles as a dying flame tribute to the olden days that we few old dusty cowboys reminisce of here in the lonely forgotten corner of the web that time forgot.

May my member be ever throbbing here.

In my research to document everything I can for this undocumented PC, I have received permission from the authors of this doujin to publish these online since BEEP no longer sells these magazines.  I specifically asked two times to get copies from BEEP and copies from the authors.  I explained I'm trying to make a 1:1 PSU replacement they were very nice and scanned them for me.  The information is extremely helpful and cuts out a substantial amount of my guesswork.  I will return the favor for them by mailing my gotek pcbs to them for free.

When I start editing the towns wiki page I'll include everything worthwhile here in English.  I'm about 99.999% sure nobody here can read Japanese without a translation tool. So I can help with this since I can read it at maybe a grade 2 level.

Things to note include:

-that the Desktops use the EXACT same power supply except the connector and wiring arrangement are different.
-Using CF cards as a hard drive
-capacitor list for fresh computer
-all power supply capacitor lists for every single towns computer. UX, TOWER, FRESH, DESKTOPS
-PSU pinouts specifically for the MX/HR/HG/MA desktops and Fresh desktops...lists even part numbers for the connectors!

-using an IOS midi device instead of a MIDI synthesizer
-different graphics cards for the towns
